Hi Jürgen - You have diagnosed the problem correctly. It's specific to the case when you have 1 DWI run only. I committed a bug fix for this. For now you can get it from here (and it should get merged into the dev version in a couple of days): https://raw.githubusercontent.com/ayendiki/freesurfer/trcdev/scripts/trac-preproc
Can you please save this version of trac-preproc to your $FREESURFER_HOME/bin/ and tell us if it fixes the problem? Thank you for bringing this to our attention. Best, Anastasia. ________________________________ From: freesurfer-boun...@nmr.mgh.harvard.edu <freesurfer-boun...@nmr.mgh.harvard.edu> on behalf of juergen.haen...@upd.unibe.ch <juergen.haen...@upd.unibe.ch> Sent: Wednesday, October 27, 2021 8:19 AM To: freesurfer@nmr.mgh.harvard.edu <freesurfer@nmr.mgh.harvard.edu> Subject: [Freesurfer] TRACULA error wrt to dwi_orig_las.1.bvals file External Email - Use Caution Dear TRACULA experts I try to run TRACULA FS7.2 on a Linux machine and get the following error (see below).
