Program difx2mark4 creates a Mk4 output fileset from the DIFX (also known as SWIN) format visibilities created by mpifxcorr and several other files carrying information about the observation. When run, difx2mark4 requires the following files to be present:
.difx/
.input
.im
.vex
Note that difx2mark4 expects to see difx v2.0 model files. All the input files to difx2mark4 are expected to be in the current working directory. With difx2mark4 version 1.0 multiple correlator output files can *not* be combined into a single destination mk4 fileset; this feature may be added in the near future, though. (The mk4 program called fourmer can be used to merge together the resultant mk4 filesets).
A mk4 fileset consists of a set of files all having the same 6 character alphabetic suffix, which is generated automatically based upon the current time, and which serves to keep filesets easily associated. Within the fileset there will be one ASCII pseudo-vex root file, named <source>.suffix. There will be one binary type 1 file for each correlated baseline, named e.g. QZ..suffix for stations Q and Z. There will also be a binary type 3 file for each station, named e.g. Q..suffix for some station Q.
difx2mark4 should be invoked from the command line as follows:
difx2mark4
[ options ] [ baseFilename ]
baseFilenameX is the prefix of a jobfile to convert; it is OK to use the .difx
filename instead
other options currently supported include:
-h
or тАУhelp
: print usage information and exit-v
or тАУverbose
: increase verbosity of output; use twice or thrice to get even more-e
nnnn : put the output in a directory for experiment nnnn (defaults to 1234)-d
or тАУdifx
: run on all .difx files in the directory, in which case the baseFilename is not necessaryтАУoverride-version
: runs even in the event of a mismatch of the difx2mark4 version and the datafile version-r
or тАУraw
: run in raw mode, which suppresses normalization-k
or ''тАУkeep-order' : don't sort antenna order into alphabeticExplicitly convert all scans from job 3327_20 into (possibly multiple) mk4 filesets:
difx2mark4 3327_20
Convert all data in .difx sub-directories into mk4 scans in expt. directory 4567, with verbosity level one:
difx2mark4 -v -d -e 4567
As needed, you can adjust the mapping of stationcodes.
