    Hi, I was happy reducing all my Gemini data with Eureka, but I received new GMOS data and I had to migrate to Astroconda-Pyraf.
    Now I’m stacked with an following error after running gsreduce. Please
    see the file attached.
    I’m working with IRAF 2.16 and Gemini 1.14.
    I would appreciate any help.
    thanks

    Someone reported seeing this message once before, but didn’t provide any follow-up information to help understand why it happened. I believe it indicates that your MDF file is missing a slitpos_mx column; is that the case? As on the previous occasion, your MDF files seem to be missing from the archive, for some reason. Where did you get this MDF file? Are you sure it isn’t really the ODF (from which the MDF is supposed to be generated)? I can’t see where it’s coming from because your log just has “Using already gprepared image gN20170927S0279”.

    Thanks,

    James.

    Hi James,
    thanks for your answer.
    Yes, you’re right it is not the MDF file but the ODF. I could not find the MDF file in the Gemini archive. Please let me know how can I get the proper file.
    regards,

    Thanks for confirming that this is due to using the ODF file. I’ll ask GN why the MDF is missing.

    It seems that a manual step involved in your MDF reaching the archive had been overlooked. You should now be able to find GN2017BQ050-01.fits there.

    Hi James,
    thanks for your mail.
    I’ve already downloaded the MDF file and I began the reductions from scratch, but I’ve got the same error again. Please find attached the gsreduce output file. I sincerely do not know what is wrong.
    regards

    There isn’t an output file attached to your last post…

    Have you changed “mdfdir” to your working directory (eg. “./”) in which GN2017BQ050-01.fits is the newly-downloaded MDF file? You could also set “mdffile=GN2017BQ050-01”, though I think it should figure that out from the headers.

    Hi again,
    I’m sorry I forgot to attach the file.
    Despite I never used the mdffile variable in my previous reductions, I followed your advice and I set mdffile = GN2017BQ050-01.
    I obtained the same error.
    Please see the file attached.
    Regards and thanks again.

    Hello,

    You’re getting the same error because it’s re-using the existing gN20170927S0279.fits. Try deleting that file and also setting “mdfdir=./” (or wherever you put GN2017BQ050-01.fits, if not in the current working directory).

    Hope that helps!
