Section 6. GARG*/EARG* Data Extraction Programs (DOS)
SonTek/YSI
All binary data files generated by the Argonaut, whether collected using the real-time data
collection software ARGONAUT or recorded internally in Argonaut memory, use the same format.
The precise format of the binary data files is given in the Argonaut Operation Manual. Several
DOS-based programs are provided to extract different portions of the Argonaut binary data and
convert the data to an ASCII text format.
Note: Two versions exist for most of the data extraction programs – GARG*.EXE and EARG*.EXE.
The only difference between the two versions is the measurement unit. Programs beginning with
a “G” extract the data in metric units; those beginning with “E” extract the data in English units.
For simplicity in examples, only the “G” programs will be illustrated.
• GARGCTL / EARGCTL – Extracts the file configuration and setup information (recorded once for
each data file).
• GARGSAMP / EARGSAMP – Extracts all data recorded with each Argonaut sample.
• GARGAMP / EARGAMP – Extracts raw signal strength data.
• GARGVEL / EARGVEL – Extracts velocity data as individual components (Beam, XYZ, ENU).
• GARGSTD / EARGSTD – Extracts velocity standard deviation data.
• GARGPRES – Extracts pressure time-series data (if collected by optional sensor).
Entering the name of any program from a DOS prompt without any parameters causes the
program to display its command syntax.
6.1. Control File Extraction: GARGCTL / EARGCTL
GARGCTL (or EARGCTL) extracts the hardware configuration and user setup information from a
binary data file. It is used by entering either of the commands below.
GARGCTL
GARGCTL
File names must be given without extension. The program assumes that the Argonaut data file
has extension .ARG and assigns the output data file the extension .CTL. For example,
GARGCTL TEST HEADER
extracts the configuration information from Argonaut binary data file TEST.ARG and places it into
an ASCII file named HEADER.CTL. If is not specified, the program will create an
output file with the same name as the Argonaut data file (i.e., TEST.CTL). The information in the
.CTL file is in a self-explanatory ASCII text format.
6.2. Sample Data Extraction: GARGSAMP / EARGSAMP
GARGSAMP (or EARGSAMP) extracts all data recorded with each Argonaut sample. This information
includes time, velocity, standard deviation, signal amplitude, compass data, temperature,
pressure, and diagnostic data. The file will show 0 for any data where the sensor is not installed
(i.e. compass/tilt or pressure sensor). The command format is as follows.
