I was hoping the developers might be able to help with a problem I'm having with a sub-step of preproc-sess.


I executed the following:

 

preproc-sess -s FS_T1_501 -surface self lhrh -fwhm 6 -per-run -fsd bold

In the relevant output, I see mktemplate-sess completed, followed by a call to mkbrainmask-sess, which eventually reported:

It's not obvious from the tail end of the output that this didn't work out, but this process finished in just a couple of seconds (making it unlikely that any smoothing or slice time correction was performed), and there was no brain_mask.nii file to be found either in /tmp/ or in the session folder. Those "not found" errors seem relevant, but I can't imagine what to do about them.
