Section 9. Autonomous Data Conversion
The following ADVField autonomous data conversion programs extract and convert specific por-
tions of the data from the binary files stored on the internal recorder to easily read ASCII files.
•
GADVCTL - Extracts file configuration and setup information.
•
GADVHDR - Extracts burst header and burst statistics data.
•
GADVTS - Extracts time series data, including velocity and diagnostic parameters.
•
GADVLIST - Extracts optional LISST sensor data.
Files stored on the recorder use a different format than those created using the real-time data ac-
quisition software. The reasons for this are:
• More information is needed to describe ADV operation during autonomous deployments.
• The need to time-stamp data using the real-time clock. (In real-time mode, the software relies
on the sampling clock used to determine sampling frequency, but this clock is too inaccurate
for long-term autonomous deployments.)
• Support for temperature and pressure measurements.
• Minimization of storage requirements (i.e., data stored in binary format).
If the name of any of these programs is entered by itself, the program displays information on its
use and a description of the parameters specified on the command line. These programs can be
run from any PC-compatible computer using the DOS operating system.
Each time a new deployment is started (e.g.,
DEPLOY command), a new file is created on the re-
corder. The file name is constructed by appending a 3-digit sequence number to the deployment
name specified with the
DEPLOYMENT command. For example, if the deployment name is WAVES ,
the first time the
DEPLOY command is used, a file named WAVES001.ADR will be created. If subse-
quent deployments are initiated with the same deployment name, new files will be created with
increasing sequence numbers (i.e.,
WAVES002.ADR , WAVES003.ADR , …).
Be aware that the data conversion software will overwrite an existing file of the same name
without prompting you for confirmation. Since the output files always use the same file name
extensions, and normally use the same name as the binary data file, this is not usually a concern.
If you modify any of the output files during analysis, be careful that the modified file is not acci-
dentally overwritten when extracting other portions of the data.
9.1. Extracting Setup and Configuration Data (GADVCTL)
The
GADVCTL program extracts the configuration information stored at the beginning of each
autonomous ADVField data file. The output from
GADVCTL is in a self-explanatory ASCII text
format. The command syntax is:
GADVCTL [ADV data file] [output file]
File names must be given without an extension. The program assumes the autonomous ADV data
file has extension
.ADR and it assigns the extension .CTL to the output file. For example,
GADVCTL WAVES001 TEST
extracts the configuration information from WAVES001.ADR and places the output in an ASCII file
named
TEST.CTL . If [output file] is not specified, the program creates an output file with the
same root name as the ADV data file. For example,
GADVCTL WAVES001
stores the configuration information into the output file WAVES001.CTL .
