The problem might actually lie with preprocessing.
Just looking at file sizes, the
fmcpr.sm4.mni305.2mm.b0dc.nii.gz file size for hc016 is 471kb, but it's ~46mb for other subjects. The
lh and
rh files for hc016 are also pretty small compared to other subjects. Not sure what's causing this.
This is the preproc command I used:
preproc-sess -s hc016 -surface fsaverage lhrh -mni305 -fwhm 4 -per-run -fsd msit -nostc -b0dc -force
Thanks for your help!

I'm only getting the error for
mni305 (
lh and
rh analyses are completing without a hitch). I have re-preprocessed and attempted to run the analysis several times, but without any success. It's not clear what the error means or what's causing it.
Thank you for any help,
Afsana
