[Freesurfer] posting a question again

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.
