Does it work if you don't use projfrac? We have a bug in the make_average_subject code that causes the average thickness (lh.avg_thickness) to be painted on the last subject in the list instead of the averaage subject. One work-around until we get this fixed is to convert the avg_thickness to the average subject with mri_surf2surf. This will require a new version of surf2surf, which you can get from:

ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mri_surf2surf

Run it with --tfmt curv

Dear all,

I've been waiting for an answer to the following question.

I am trying to overlay group-averaged data (FSL) on an averaged anatomical
brain (Freesurfer).
I did the following,

mri_vol2surf --src AVG.gfeat/cope1.feat/thresh_zstat1.img --src_type analyze
--srcreg register.dat --hemi lh --projfrac 0.5 --out
AVG.gfeat/cope1.feat/thresh_zstat1-lh.w --out_type paint

and got the following error message,

MRISreadCurvature: could not open
/home/nam/AVERAGE/average/surf/lh.thickness
No such file or directory

In the surf directory, I DID find "lh.avg_thickness".
I renamed "lh.avg_thickness" "lh.thickness", but it didn't work.
Would someone please let me know how to remedy this?

  
Nam.
