Indeed. Doug sent you a modified version of trac-preproc, which is a script that's called by trac-all. The idea was for you to overwrite $FREESURFER_HOME/bin/trac-preproc with the version that Doug sent, then run trac-all like before. Did you try that?

Hi Anastasia,

 

The problem is in 7.3, trac-all -prep -c config.file is looking for ThalamicNuclei.v12.T1.FSvoxelSpace.mgz  from segmentThalamicNuclei.sh which doesn’t exist.

Because in v7.3, segmentThalamicNuclei.sh output a new version v13 (ThalamicNuclei.v13.T1.FSvoxelSpace.mgz).

 

Thanks,

 

King-Wai

Hi King-Wai - You are not supposed to run trac-preproc directly. Run trac-all -c configfile, like before.

 

Anastasia.

Hi Douglas,

 

Thank you for looking into this.

It gives the following error.

 

trac-preproc.sh -c config.file

intrareg: Undefined variable.

 

Thanks,

Can you copy the attached trac-preproc into $FREESURFER/bin and try again (after removing the link)?

Hi Anastasia,

 

Just downloaded FreeSurfer version 7.3 and trying out TRACULA.

Ran recon-all, segmentThalamicNuclei.sh, and trac-all in v7.3

However trac-all -prep is looking for ThalamicNuclei.v12.T1.FSvoxelSpace.mgz  from segmentThalamicNuclei.sh which doesn’t exist.

Because in v7.3, segmentThalamicNuclei.sh output a new version v13 (ThalamicNuclei.v13.T1.FSvoxelSpace.mgz).

I worked around this problem by linking ThalamicNuclei.v12.T1.FSvoxelSpace.mgz  to ThalamicNuclei.v13.T1.FSvoxelSpace.mgz

ln -s ThalamicNuclei.v13.T1.FSvoxelSpace.mgz ThalamicNuclei.v12.T1.FSvoxelSpace.mgz

 

trac-all finished w/o problem.

 

trac-all -version

trac-all 7.3.0

 

I seems trac-all in v7.3 forgets to update the fact that segmentThalamicNuclei.sh output v13 of the file.

Or it is looking for v12 for a reason?

 

Is my fix correct?

 

Thanks,

 

King-Wai
