This directory contains two programs, out2sud and dat2sud, to convert
acquired data to SUDS format.  out2sud converts the binary .hdr and
.out files produced by simp and scope, while dat2sud works on
binary .dat files.

SUDS is a standardized data format sanctioned by the IUGG/IASPEI
organization.  There are many downstream processing programs supplied
by this organization that can be used to further analyze SUDS data.

To use out2sud, first run simp or scope with output files on and
simp OutputFileFormat set to OUT.  This will create a binary .hdr
and .out data files.  The .hdr file has information about the number
of channels and other items that help downstream processing analyze
the raw data files.

Next, to convert one of the .out binary data files, run

> out2sud simp.hdr 00000000.out sudsout.dmx

where 00000000.out would be the typical .out file name for sequential
output files.  The out2sud conversion program will create the fully
demuxed sudsout.dmx file ready for further IASPEI processing.

Run out2sud with no arguments to get a usage message showing the
required arguments and listing the available command line options.


To use dat2sud, first run simp with the OutputFileMode set to
SEQUENTIAL and the OutputFileFormat set to DAT.  This will create
binary .dat data files with numerically increasing names that contain
both header and analog data information (and optionally GPS
information).

Next, to convert the .dat binary data files, run

> dat2sud 00000000.dat sudsout.dmx

where 00000000.out would be the typical .out file name for sequential
output files.  The dat2sud conversion program will create the fully
demuxed sudsout.dmx file ready for further IASPEI processing.

Time information is taken from the .DAT header fields.  By default,
simp fills these time and date fields with a calculated time value.
It determines this time by reading a start time from the PC and then
adding the theoretical time for each buffer of acquired data.  When
simp is used with GPS support enabled, highly accurate GPS times are
stored in the file.  The PARGPS utility program calctime can be used
to update the .DAT header fields with this GPS time.

Note: The dat2sud program can be compiled with or without GPS support.
To recompile with GPS support, be sure the PARGPS software is installed
and add USE_GPS="Yes" to the convert\ascii make or nmake command line.
Or, from the top level, change the makeall file GPS_YES_OR_NO value
from "No" to "Yes" and run makeall.



* BUILDING THE SUDS CONVERSION PROGRAMS

Building the out2sud and dat2sud conversion programs requires files
from the SUDS utility library.  Source code for the SUDS library is
included in this directory in case you want to rebuild.

The SUDS library is only designed to be compiled 32 bits or 16 bit
large model.  Other 16 bit memory models are not supported.



* OUT2SUD /G OPTION FOR VISEIS USERS

The out2sud conversion program can also be used with .out files
produced by PC Systems Design's ViSeis program for Windows.  The
ViSeis .out files typically contain additional GPS time stamp
information stored in the first few samples of channel 0.  Run out2sud
with the /g command line option to use this GPS time stamp instead of
the default OS file time stamp during conversion.  For example,

> out2sud /g viseis.hdr 00000000.out sudsout.dmx
