Difficulty with batch_process/6_singlesubjectRSFC
Hello,
I am using the Fcon1000 scripts on my own data to run a seed-based RSFC analysis. The data have already been pre-processed. I created a left PCC seed using 3dcalc in AFNI.
When I run batch_process with the single-subject RSFC option selected, I receive this output/error message for each subject (see my note in caps early in the output):
--------------------------
running subject MJ0099
--------------------------

I have run this multiple times and the error messages are slightly different each time, but the theme is that it keeps saying "failed to find header....". I am not sure why it seems like some lines are overwritten a few times in the text.
I previously ran this and it created a (seed).1D file in "seed_ts" for each subject (although it did create an entirely new subject folder to do so...). Since it created that file, I thought it had worked, but I came to find that the (seed)_corr.nii.gz, (seed)_Z_2standard.nii.gz, and (seed)_Z.nii.gz files were not created in the individual subjects' RSFC directories.
I have done my best to check for spelling errors etc, and of course I could have missed one!
Any guidance would be appreciated. My scripts/files are copied below.
Thanks,
Megan

RE: Difficulty with batch_process/6_singlesubjectRSFC
Hello,
the error message indicates that it can't find a certain file. So it's either not created, or there is a typo somewhere in where you specify your paths. Did you double check batch_list_MK.txt?
Is the file where you expect it to be?
