Hi Anastasia,

I'm re-running tracula by using new version 5.3.

In the step 3 (trac-all -inter -c $FREESURFER_HOME/configurazion_file) I have this error:

MRISregister() return, current seed 0

writing registered surface to /Applications/freesurfer/subjects/subject_prova/Diff01/surf/rh.cvs.tocvs_avg35.sphere.reg...

expanding nbhd size to 1

1110: 1 negative triangles

I'm attaching the configuration file that I have used.

What's happened?

Thank you very much,

Stefano
