Susanne,
Which distribution of freesurfer are you using? You can find out by typing:
cat $FREESURFER_HOME/build-stamp.txt
A segmentation fault problem is a difficult one to track down, so I will start by sending you a newer build of mri_surf2surf (one that also contains debugging info).

Hi,
I am relatively new to freesurfer and trying to do my first group analysis. Following the web tutorial -although with my own data set- I was able to do the pre-processing incl. mris_preproc which created the desired output without any error message. However, when I try to perform the next step, i.e. smoothing the data, I get the following error message
mri_surf2surf --hemi lh --s average --sval lh.ADvsContr ols.thickness.mgh --fwhm 10 --tval lh.ADvsControls.thickness.10.mgh
srcsubject = average srcval = lh.ADvsControls.thickness.mgh srctype = trgsubject = average trgval = lh.ADvsControls.thickness.10.mgh trgtype = surfreg = sphere.reg srchemi = lh trghemi = lh frame = 0 fwhm-in = 0 fwhm-out = 10 Reading source surface reg /cind/00/FAD/subjects/average/surf/lh.sphere.reg Loading source data INFO: trgsubject = srcsubject reading group avg surface area 922 cm^2 from file Segmentation fault
I also tried to run the smoothing as a part of the mris_preproc with the same result. I am using the v3.0.5 version of freesurfer. Any help to figure out what I am doing wrong or what else is going on would be greatly appreciated.
