[Freesurfer] 3dvolreg Error for preproc-sess

Hi all,

I'm running version 5.2 off-site, and I keep running up against an error for preproc-sess. From my SUBJECTS_DIR, I am running

preproc-sess -fsd bold -s 608_Sess1 -fwhm 5 -per-run

which provides the following error:

3dvolreg.afni: symbol lookup error: 3dvolreg.afni: undefined symbol: afni_ncerr ERROR: 3dvolreg.afni Invalid null command.

I found this old communication https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg28736.html in which this user had the same problem. I found 3dvolreg.afni in the Freesurfer "bin" folder and copied to to my AFNI folder, but I still get the same error when running preproc-sess, even with 3dvolreg.afni now in the AFNI cluster.

Any idea what the problem might be?

Best, Adam Nitenson
