      +

      5.3.4. Importing data in CSV format

      +

      A comma-separated file (.csv) can be used to import dive information either as dive profiles +(as in the case of the APD Inspiration and Evolution closed circuit rebreathers) or as dive +metadata (in case the user keeps dive data in a spreadsheet). The CSV format is a universal +simplified format that allows for easy information exchange between different computers or +software packages. For an introduction to CSV-formatted files see A Diver’s +Introduction To CSV Files. Subsurface dive logs can also be exported in CSV format to +other software that reads this format. See APPENDIX D: Exporting a spreadsheet +to CSV format for information that may be helpful for importing spreadsheet-based data +into Subsurface.

      +
      +
      Importing dives in CSV format from dive computers or other dive log software
      +

      One can view a CSV file by using an ordinary text editor. It is normally organised into +a single line that provides the headers (or field names or column headings) of the data +columns, followed by the data, one record per line.

      +

      There are two types of CSV dive logs that can be imported into Subsurface:

      +

      1. -Which character separates the different columns within a single line of -data? This field separator should be either a comma (,) or a TAB character. -This can be determined by opening the file with a text editor. If it is -comma-delimited, then the comma -characters between the values are clearly visible. If no commas are evident and -the numbers are aligned in columns, -the file is probably TAB-delimited (i.e. it uses a TAB as a field separator, as -in the above example). +CSV dive details: This dive log format contains similar information to that of a + typical written dive log, e.g. dive date and time, dive depth, dive duration, names of + buddy and dive master and perhaps some information about cylinder pressures before and + after the dive, as well as a comment or two about the dive. All the data for a single + dive go on a single line of text, following the order of the column headings.

      2. -Which data columns need to be imported into Subsurface? The Dive Time and -Depth columns are always required. Open the file using a text editor and note -the titles of the columns to be imported and their column positions. For -instance for the above example: +CSV dive profile: This dive log format includes much more information about a single + dive. For instance there may be information at 30-second intervals, indicating depth, water + temperature at that depth, and cylinder pressure at that moment in time. Each line contains + the information for a single instant in time during the dive, 30 seconds after that + of the previous instant. Many lines + are required to complete the depth profile information for a single dive. This is a common + export format used by closed-circuit rebreather (CCR) dive equipment and many software + packages that handle dive computer data and/or dive logs.

        Time:           column 1
-Depth:          column 2
-Temperature:    column 5
-pO₂:          column 4
        -
      -

      Armed with this information, importing the data into Subsurface is -straightforward. Select -Import→Import Log Files from the main menu. In the resulting file -selection menu, select CSV files, after which a common configuration dialog -appears for all the -files with a CSV extension:

      -
      -
      -FIGURE: CSV download dialogue -
      -
      -

      There are pre-configured definitions for some dive computers, e.g. the APD -rebreathers. If the user’s dive computer is on this list, it should be selected -using the dropdown -box labeled Pre-configured imports. Select the button at the bottom right -to indicate whether the dive data are in metric of imperial units. -Finally OK should be clicked and -the dive will be imported and listed in the Dive List tab of Subsurface.

      -

      If the dive computer is not on the pre-configured list, the user must -select the Field -Separator (TAB or comma) for the particular CSV file, using the appropriate -dropdown list. and indicate which columns in the CSV file -contain which data -variables. For each data column used for import, the user must check the -appropriate check box -and indicate in which column these data are found. For instance, the image above -corresponds to the dialogue that would apply to the CSV data set described above -the image. After completing the column specification, select the OK button -and the dive will be imported and listed in the Dive List tab of Subsurface.

      4.3.6. Importing dives from manually kept CSV file

      -

      If one keeps dive logs in a spreadsheet, there is an option to import -those dives as well. Spreadsheet data, exported as a CSV file, can -be imported to Subsurface. When importing manually -kept log files, the information needed is quite different as we are -importing only metadata, not profile samples.

      -

      Similarly to importing dives in CSV format (see above), one needs to -know the internal format -of the CSV data to import.

      +

      Before being able to import the CSV data to Subsurface one needs to know a few +things about the data being imported:

      1. Which character separates the different columns within a single line of -data? This -should be either a comma (,), semicolon (;) or a TAB -character, and could be determined by opening the file with a text -editor. If it is comma-delimited, then the comma -characters between the values are clearly visible. If no commas are evident and -the data -are in clear columns, the file -is probably TAB-delimited (i.e. it uses a TAB as a field separator, as in the -above example). -A recommended field separator for the export is tab, as commas might be part of -the -field values themselves. Therefore the use of an appropriate field separator -in very important. + data? This field separator should be either a comma (,) or a TAB character. + This can be determined by opening the file with a text editor. If it is + comma-delimited, then the comma + characters between the values are clearly visible. If no commas are evident and + the numbers are aligned in columns, + the file is probably TAB-delimited (i.e. it uses a TAB as a field separator).

      2. -Which columns need to be imported into Subsurface? We do not -currently have any mandatory input fields, but some, e.g. dive duration -are crucial for the log file to make any sense. Possible options -can be seen in the image below and one should include all the -fields available in both your log file and in the Subsurface -import. +Which data columns need to be imported into Subsurface? Is it a CSV dive details + file or a CSV dive profile file? Open the file using a text editor and note + the titles of the columns to be imported and their column positions.

      3. -Units used for depth, weight and temperature. We consider depth to be -either feet or meters, weight kilograms or pounds and temperature either -Celsius or Fahrenheit. However, the users can select Metric or -Imperial in the Preferences tab of Subsurface. No mixture of unit -systems is allowed for the different fields. +Is the numeric information (e.g. dive depth) in metric or in imperial unis?

      -

      Importing manually kept CSV log files is quite straight forward, but -there might be many fields and counting the field numbers is error -prone. Therefore validation of the data to be imported is critical.

      -

      To import the dives, select Import→Import Log Files from the menu -bar. If the CSV option in the dropdown list is selected and the file list -includes file names ending with .CSV, one can select the -Manual dives tab that will bring up the following configuration dialog:

      +

      Armed with this information, importing the data into Subsurface is +straightforward. Select +Import → Import Log Files from the main menu. In the resulting file +selection menu, select CSV files (towards the bottom right). This shows all .CSV files in the selected +directory. Select the file that needs to be imported. A configuration panel +appears as depicted below:

      +
      +
      +FIGURE: CSV download dialogue 1 +
      +
      +

      Notice that, at the top left, there is a dropdown list containing pre-configured +settings for some of the more common dive computers and software packages +encountered by divers. If the CSV file being imported originated from any of +these pre-configured items, then select it. Otherwise use the Manual Import +option. The configuration panel also has dropdown lists for the specification of the appropriate +field separator (Tab, comma or semicolon), the date format used in the CSV file, +the time units (seconds, minutes or minutes:seconds), as well as the unit system +(metric or imperial). Selecting the appropriate options among these is critical for +the successful import of the data.

      +

      The last remaining task is to ensure that all the data columns have the appropriate +column headings. The top line of the white part of the data table contains the column +headings found in the CSV data file. The blue row of cells immediately above these +contains the names understood by Subsurface. The white area below the dropdown +lists contains all the field names that Subsurface recognises. These names are +in blue balloons and can be moved using a drag-and-frop action. For +instance, Subsurface expects the column heading for Dive number (" # ") to be "Dive # ". If +the column heading that Subsurface expects is not in the blue cells, then drag the +appropriate column heading from the upper area and drop it in the appropriate blue +cell at the top of the table. To indicate the correct column for "Dive #", drag +the ballooned item labelled "Dive # " and drop it in the blue +cell immediately above the white cell containing " # ". This is depicted in +the image below.

      -FIGURE: Download dialog for Manual CSV logs +FIGURE: CSV download dialogue 2 +
      +
      +

      Continue in this way to ensure that all the column headings in the blue row of +cells correspond to the headings listed in the top part of the dialogue. Having +completed this task, select the OK button to the bottom right og the dialogue. +The data from the CSV file are imported and shown in the Dive List panel.

      A Diver’s Introduction to CSV Files

      +
      + + + +
      +Important +CSV is an abbreviation for a data file format: Comma-Separated Variables. It is a +file format allowing someone to view or edit the information using a text editor such +as Notebook (Windows), gedit (Linux) or TextWrangler (OS/X). The two main advantages of +the CSV format is that the data are easily editable as text without any proprietary software +and ensuring all information is human-readable, not being obscured by any custom or +proprietary attributes that proprietary software insert into files. +Because of its simplicity the CSV format is used +as an interchange format between many software packages, e.g. between +spreadsheet, statistical, graphics, database and diving software. Within Subsurface, CSV files can also +be used to import information from other sources such as spreadsheet-based dive logs and +even from some dive computers.
      +
      +

      CSV files can be created or edited with a normal text editor. The most important attribute of a +CSV file is the field separator, the character used to separate fields within a single line. The +field separator is frequently a comma, a colon, a SPACE character or a TAB character. When exporting data from +spreadsheet software, the field separator needs to be specified in order to create the CSV file. CSV files are +normally organised into a single line that provides the headers (or field names) of the data columns, +followed by the data, one record per line. Note that each field name +may comprise more than one word separated by spaces; for instance Dive site, below. Here is an example of +dive information for four dives using a comma as a field separator:

      +
      +
      +
      Dive site,Dive date,Time,Dive_duration, Dive_depth,Dive buddy
+Illovo Beach,2012-11-23,10:45,46:15,18.4,John Smith
+Key Largo,2012-11-24,09:12,34:15,20.4,Jason McDonald
+Wismar Baltic,2012-12-01,10:13,35:27,15.4,Dieter Albrecht
+Pulau Weh,2012-12-20,09:46,55:56,38.6,Karaeng Bontonompo
      +
      +

      In this format the data are not easily read by a human. Here is the same information in TAB-delimited format:

      +
      +
      +
      Dive site       Dive date       Time    Dive_duration   Dive_depth      Dive buddy
+Illovo Beach    2012-11-23      10:45   46:15   18.4    John Smith
+Key Largo       2012-11-24      09:12   34:15   20.4    Jason McDonald
+Wismar Baltic   2012-12-01      10:13   35:27   15.4    Dieter Albrecht
+Pulau Weh       2012-12-20      09:46   55:56   38.6    Karaeng Bontonompo
      +
      +

      It is clear why many people prefer the TAB-delimited format to the comma-delimited format. The +disadvantage is that one cannot see +the TAB characters. For instance, the space between Dive and date in the top line may be +a SPACE character or a TAB character (in this case it is a SPACE character: the tabs are before and +after Dive date). If the field names in the first line are long, the alignment with data in the other lines +cannot be maintained. Here is a highly simplified and shortened TAB-delimited example of a CSV dive log +from an APD closed-circuit rebreather (CCR) dive computer:

      +
      +
      +
      Dive Time (s)   Depth (m)       pO₂ - Setpoint (Bar)  pO₂ - C1 Cell 1 (Bar) Ambient temp. (Celsius)
+0       0.0     0.70    0.81    13.1
+0       1.2     0.70    0.71    13.1
+0       0.0     0.70    0.71    13.1
+0       1.2     0.70    0.71    13.2
+0       1.2     0.70    0.71    13.1
+10      1.6     0.70    0.72    12.7
+20      1.6     0.70    0.71    12.6

+40      1.8     0.70    0.68    12.5
      +
      +

      When a CSV file is selected for import, Subsurface displays the column headers as well as some of the data +in the first few lines of the CSV file, making it much easier to work with CSV files. +CSV files can therefore be used in many contexts for importing data into a Subsurface dive log. +Knowledge of a few basic things about the content of the CSV file allows a smooth import +of the dives into Subsurface.

      +
      +
      + + + +
      +Important +The CSV import has a couple of caveats. One should avoid some special characters +like ampersand (&), less than (<), greater than (>) and double quotes (") as part +of the numbers or text within a cell. The +file should use UTF-8 character set, if using non-ASCII characters. Also the +size of the CSV file might cause problems. Importing 100 dives at a time +(CSV dive details) works, but larger files might exceed +limits of the parser used. When encountering problems with CSV imports, first try with +a smaller file to make sure everything works.

    +
      +
    • +

      +During the dive, recording cylinder switch events. Since sidemount diving normally involves two + cylinders with air or with the same gas mixture, Subsurface distinguishes among these different + cylinders. In contrast, most dive computers that allow gas switching only distinguish among different + gases used, not among different cylinders used. This means that when sidemount dives are downloaded + from these dive computers, the events of switching between cylinders with the same gas are not downloaded. This may mean + that one may have to keep a written log of cylinder switch times using a slate, or (if the dive computer + has this facility) marking each cylinder switch with a bookmark that can be retrieved later. Returning + from a dive with the information about cylinder changes is the only tricky part of logging sidemount dives. +

    5.6.2. Closed circuit rebreather (CCR) dives

    +
    + + + +
    +Note +Closed system rebreathers use advanced technology to recirculate +gas that has been breathed while doing two things to maintain a +breathable oxygen concentration: +a) remove carbon dioxide from the gas that has been exhaled +b) regulate the oxygen concentration to remain within safe diving limits. +Currently, within Subsurface, the Poseidon MkVI Discovery is the best +supported CCR dive computer. The CCR interface of Subsurface is currently experimental +and under active development. In contrast to a conventional recreational +dive computer, a CCR system computer does not allow the download of a log +containing multiple dives. Rather, each dive is stored independently. This +means that Subsurface cannot download a dive log directly from a CCR +dive computer, but that it imports CCR dive logs in the same way that it +imports dive log data from other digital databases.
    +
    +
    +
    Import a CCR dive
    +

    See the section dealing with Importing dive information from other +digital sources. From the main menu of Subsurface, select Import → Import +log files to bring up the universal import dialogue. As +explained in that section, the bottom right +hand of the import dialogue contains a dropdown list of appropriate devices +that currently includes an option for (Poseidon) MkVI files (import for other +CCR equipment is under active development). Having selected the appropriate CCR format and +the directory where the original dive logs have been stored from the CCR dive +computer, one can select a particular dive log file (in the case of the MkVI +it is a file with a .txt extension). After selecting the appropriate dive log, +activate the Open button at the bottom right hand of the universal import dialogue.

    Partial pressures of gases: The graph of oxygen partial pressure shows the +information from the oxygen sensors of the CCR equipment. In contrast to recreational +equipment (where pO2 values are calculated based on gas composition and dive depth), +CCR equipment provide actual measurements of pO2, derived from oxygen sensors. +In this case the graph for oxygen partial pressure +should be fairly flat, reflecting the setpoint settings during the dive. The mean +pO2 is NOT the mean oxygen partial pressure as given by the CCR equipment, but +a value calculated by Subsurface as follows:

    +
      +
    • +

      +For TWO O2 sensors the mean value of the two sensors are given. +

      +
      • +
    • +

      +For THREE-sensor systems (e.g. APD), the mean value is also used. However + differences of more than 0,1 bar in the simultaneous readings of different sensors are + treated as spurious. If one of the three sensors provides spurious data, it is ignored. +

      +
      • +
    • +

      +If no sensor data is available, the pO2 value is assumed to be equal to the setpoint. +

      +
      • +
    +

    The mean pO2 of the sensors is indicated with a green line,

    +

    The oxygen setpoint values as well as the readings from the individual +oxygen sensors can be shown. The display of additional CCR information is turned on by +checking the appropriate checkboxes in the Preferences panel (accessible by +selecting File → Preferences → Graph). This part of +the Preferences panel look like this, representing two checkboxes that modify +the display of pO2 when the appropriate toolbar button on the Dive Profile +has been activated.

    +
    +
    +FIGURE: CCR preferences panel +
    +
    +

    Checking any of the check boxes allows the display of additional oxygen-related +information whenever the pO2 toolbar button on the Profile panel is activated. +The first checkbox allows the display of setpoint information. This is a red line +superimposed on the green oxygen partial pressure graph and allows a comparison of the +mean measured oxygen partial pressure and the setpoint values, as in the image below.

    +
    +
    +FIGURE: CCR setpoint and po2 graph +
    +
    +

    The second checkbox allows the display of the data from each individual oxygen sensor +of the CCR equipment. The data for each sensor is colour-coded as follows:

    +
      +
    • +

      +Sensor 1: grey +

      +Sensor 3: brown +

      +
      • +

    The mean oxygen pO2 is indicated by the green line. This allows the direct comparison +of data from each of the oxygen sensors, useful for detecting abnormally low or erratic +readings from a particular sensor.

    +

    +FIGURE: CCR sensor data graph +

    The setpoint data can be overlaid on the oxygen sensor data by activating both of the above +check boxes. Partial pressures for nitrogen (and helium, if applicable) are shown in the +usual way as for open circuit dives.

    +

    Events: Several events are logged, e.g. switching the mouthpiece to open circuit. +These events are indicated by yellow triangles and, if one hovers over a triangle, +a description of that event is given as the bottom line in the Information Box.

    +

    Cylinder pressures: Some CCR dive computers like the Poseidon MkVI record the +pressures of the oxygen and diluent cylinders. The pressures of these two cylinders +are shown as green lines overlapping the depth profile. In addition, start and +end pressures for both oxygen and diluent cylinders are shown in the Equipment Tab. +Below is a dive profile for a CCR dive, including an overaly +of setpoint and oxygen sensor data, as well as the cylinder pressure data.

    18. APPENDIX D: Exporting a spreadsheet to CSV format

    +
    +

    Many divers keep a diving log in some form of a digital file, commonly a spreadsheet +with various fields of information. These logs can be easily imported into Subsurface after the +spreadsheet is converted in a .CSV file. +This section explains the procedure to convert a diving logbook stored in a spreadsheet +to a .CSV file that will later be imported from Subsurface. +Creating a .CSV is a straightforward task, although the procedure is somewhat different +according to which spreadsheet program is used.

    +

    The first step is to organize the diving data in the spreadsheet, so that the first row +contains the names (or titles) of each column and the information for each dive is stored in a single row. +Subsurface supports many data items (Dive #, Date, +Time, Duration, Location, GPS, Max Depth, Mean Depth, Buddy, Notes, Weight and Tags). +The user can organize dive data following a few simple rules:

    +
      +
    1. +

      +Date: use one of the following formats: yyyy-mm-dd, dd.mm.yyyy, mm/dd/yyyy +

      +
      2. +
    2. +

      +Duration: the format should be minutes:seconds. +

      +
      3. +
    3. +

      +Unit system: only one unit system shold be used (i.e., no mixture between imperial and metric units) +

      +
      4. +
    4. +

      +Tags and buddies: values should be separated using a comma. +

      +
      5. +
    5. +

      +GPS position: users must use decimal degrees, e.g. 30.22496 30.821798 +

      +
      6. +
    +
    +

    18.1. LibreOffice Calc and OpenOffice Calc

    +

    These are open source spreadsheet applications forming parts of larger open source office suite applications. The user interaction with LibreOffice and OpenOffice is very similar. +In Libreoffice Calc the time format should be set to minutes:seconds - [mm]:ss and dates should be set to one of: yyyy-mm-dd, dd.mm.yyyy, mm/dd/yyyy. A typical dive log may look like this:

    +
    +
    +FIGURE: Spreadsheet data +
    +
    +

    To export the data as a .CSV file from within LibreOffice click File → Save As. On the dialogue that comes up, select the Text CSV (.csv) as the file type and select the option Edit filter settings.

    +
    +
    +FIGURE: Save as options +

    18.2. Microsoft Excel

    +

    The field delimiter (called "list separator" in Microsoft manuals) is not accessible +from within Excel and needs to be set through the Microsoft Control Panel. After changing the +separator character, all software on the Windows machine use the new character as a separator. +One can change the character back to the default character by following the same procedure, outlined below.

    +
      +

      +In Microsoft Windows, click the Start button, and then select Control Panel from the list on the right-hand side. +
