Hi,
I am sorry to re-post this problem, but I cannot find the source of my problem:

During sampling the feat data to fsaverage using for example:
mris_preproc --target fsaverage --hemi lh --out  3runs/lh.cope1.mgh  --iv run1.feat/stats/cope1.nii run1.feat/reg/freesurfer/anat2exf.register.dat --iv run2.feat/stats/#cope1.nii run2.feat/reg/freesurfer/anat2exf.register.dat --iv run3.feat/stats/cope1.nii run3.feat/reg/freesurfer/anat2exf.register.dat

For one subject I get in the log file:
...
mri_surf2surf --srcsubject 1250 --srchemi lh --srcsurfreg sphere.reg --trgsubject fsaverage --trghemi lh --trgsurfreg sphere.reg --tval 3runs/tmp.mris_preproc.13727/1250.1.mgh --sval 3runs/tmp.mris_preproc.13727/subjsurfvals.mgh --noreshape --no-cortex
ERROR: dimension inconsistency in source data
       Number of surface vertices = 132315
       Number of value vertices = 132299
...

Does it mean that the recon-all files are incompatible with the functional images?  Can this stem from some manual editing of pial surface? Where should I search to spot the problem?

Thank you a lot,
Aga
