If you run recon-all, ?h.pial will appear as symbolic links to ?h.pial.T1.
Here is the list of symbolic links you should find in your subject/surf
directory:
rh.pial -> rh.pial.T1
lh.pial -> lh.pial.T1
rh.fsaverage.sphere.reg -> rh.sphere.reg
lh.fsaverage.sphere.reg -> lh.sphere.reg
rh.white.K -> rh.white.preaparc.K
rh.white.H -> rh.white.preaparc.H
lh.white.K -> lh.white.preaparc.K
lh.white.H -> lh.white.preaparc.H
I'm wondering why the symbolic links are not created.
To create the symbolic links,
1. cd to subject/surf directory
2. run ln command to create each link, for example, 'ln -s lh.pial.T1 lh.pial'
Best,

Subject: [Freesurfer] make_average_subject command error
External Email - Use Caution
Dear Freesurfer experts,
We're trying to make an average subject for group analysis using Freesurfer
7.1, but the make_average_subject command exits with errors after calling
make_average_surf:
MakeAverageSurf(): 129 lh pial sphere.reg talairach.xfm 1 1
It appears to be trying to find the lh.pial surface for the first participant,
but this file is named "lh.pial.T1". (In FS 5.3 and 6.0, this file was labelled
"lh.pial", but with FS7.1, it seems to be named lh.pial.T1).
Does anyone have a suggestion for how to fix this problem? (We want to avoid
changing all the file names to "lh.pial" from "il.pial.T1")
Should we call make_average_subject again with -no-surf-to-surf ?
Best regards,
Asuka
