Hi,

I'm doing first level analysis in FSFAST and I'm consistently getting the following error when running fast_selxavg3():

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
