Dear Emilie,

I have tried to run it as you suggested, but it did not help. Not even the coregistration would start. The path 'C:\Users\Katka\Desktop\sikorova\20200803_140853_celer_1_1\19\pdata\1\' leads directly to my 2dseq file of one study subject. When I tried to follow your advice and first added the "20200803_140853_celer_1_1" to the subject_list, it was not able to get to the 2dseq at all. Then I moved the "1" to the subject_list and it would start the coregistration, but stopped at the same errors that I had mentioned in my first message.

Thank you,

Pavlína Sikorová
