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.
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.
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.
