Examples of using flagmanager to manipulate the flag versions of a MeasurementSet
First save the flags from a MS using flagdata
flagdata('my.ms', mode='manual', autocorr=True, flagbackup=True)
List the existing flag versions of the above MS
flagmanager('my.ms', mode='list')
The output of the above command can be seen below. Note that the first flag versions is called 'Original", which was saved at import time using importasdm. The second entry called 'flagdata_1' is the flag versions from the above manual flagging.
2018-04-23 18:47:19 INFO flagmanager::agentflagger:: + MS : /Users/casadir/work/my.ms
2018-04-23 18:47:19 INFO flagmanager::agentflagger:: main : working copy in main table
2018-04-23 18:47:19 INFO flagmanager::agentflagger:: Original : Original flags at import into CASA
2018-04-23 18:47:19 INFO flagmanager::agentflagger:: flagdata_1 : Flags autosave on 2018-04-23 20:47:14
A captured Python dictionary returns the same content but is machine readable:
myflaglist = flagmanager('myvis.ms', mode='list')
{0:{'name': 'Original', 'comment': 'Original flags at import into CASA'}, 1:{'name': 'flagdata_1', 'comment': 'Flags autosave on 2018-04-23 20:47:14'}}
Rename the flag version to a more meaningful name
flagmanager('my.ms', mode='rename', oldname='flagdata_1', versionname='autocorr', comment='Flags from autocorrelation')
Restore the original flags to the MS
flagmanager('my.ms', mode='restore', versionname='Original')
