Getting corrupt MS from mvftoms
SpheMakh opened this issue · comments
I tried to inspect the MS using CASA listobs task and got the following error:
The mvf file I used is http://stgr1.sdp.mkat.chpc.kat.ac.za:7480/1535789408/1535789408_sdp_l0.full.rdb

I've been struggling to convert this file to an MS for almost a month now. Is it possible for someone who more familiar with katdal to get me the MS from it?
The MS is on imgr-com-1 at
imgr-com-1:/data/sphe/NGC4993_SEPT01/msdir/NGC4993_OFF_SEPT0118_RAW.ms
I will have a look at this later this evening and see if it can be recovered.
@SpheMakh - looks like I have generated a valid MS (at least listobs() on it works OK). Busy copying it onto imgr-com-1 now - ETA around 2 hours - will let you know when it is done.
Thanks! @sratcliffe
Hey @SpheMakh - the data is available on imgr-com-1:
/data/sphe/NGC4993_SEPT01/input_new
Let me know how it goes...
Did you resolve this, @SpheMakh?
Yes, it was resolved.
