Processing Data
Process the data in SBE Data Processing.
1.
Convert the .hex data file created by Seasave to a .cnv file in SBE Data
Processing’s Data Conversion module.
2.
Once the data is converted, it can be further processed and plotted in
SBE Data Processing’s other modules.
Editing .hex Data File
Sometimes users want to edit the .hex data file before beginning processing, to
remove data at the beginning of the file corresponding to instrument
soak time,
to remove blocks of bad data, to edit the header, or to add explanatory notes.
Editing the .hex file can corrupt the data, making it impossible to perform
further processing using Sea-Bird software.
We strongly recommend that
you first convert the data to a .cnv file (using Data Conversion in SBE Data
Processing), and then use other SBE Data Processing modules to edit the
.cnv file as desired.
The procedure for editing a .hex data file described below has been found to
work correctly on computers running Windows 98, 2000, and NT.
If the
editing is not performed using this technique, SBE Data Processing may
reject the edited data file and give you an error message.
1. Make a back-up copy of your .hex data file before you begin.
2. Run WordPad .
3. In the File menu, select Open. In the Open dialog box: for Files of type ,
select All Documents (*.*) . Browse to the desired .hex file and click Open.
4. Edit the file as desired, inserting any new header lines after the System
Upload Time line . Note that all header lines must begin with an asterisk
(*), and *END* indicates the end of the header. An example is shown
below (for an SBE 21 data file), with the added lines in bold:
* Sea-Bird SBE 21 Data File:
* FileName = C:\Odis\SAT2-ODIS\oct14-19\oc15_99.hex
* Software Version Seasave Win32 v1.10
* Temperature SN = 2366
* Conductivity SN = 2366
* System UpLoad Time = Oct 15 1999 10:57:19
* Testing adding header lines
* Must start with an asterisk
* Place anywhere between System Upload Time & END of header
* NMEA Latitude = 30 59.70 N
* NMEA Longitude = 081 37.93 W
* NMEA UTC (Time) = Oct 15 1999 10:57:19
* Store Lat/Lon Data = Append to Every Scan and Append to .NAV
File When <Ctrl F7> is Pressed
** Ship: Sea-Bird
** Cruise: Sea-Bird Header Test
** Station:
** Latitude:
** Longitude:
*END*
5. In the File menu, select Save ( not Save As). If you are running
Windows 2000, the following message displays:
You are about to save the document in a Text-Only format,
which will remove all formatting. Are you sure you want to
do this?
Ignore the message and click Yes .
6. In the File menu, select Exit.
Note:
See the SBE Data Processing
manual and/or Help files.
Note:
Although we provide this
technique for editing a .hex file,
Sea-Bird’s strong
recommendation, as described
above, is to always convert the
.hex data file and then edit the
converted (.cnv) file.
