Mark, what context are you running it in? Ie, are you running it by itself or was it called by something else. It looks like the subject's surface and the overlay that you are smoothing have different number of vertices.

Hi all,

I've run into a snag whilst running mris_fwhm:

$ mris_fwhm --i <snip>/all.nii --s <SUBJID> --hemi rh --sum <snip>/ fwhm.sum <SUBJID> rh white Number of vertices 136129 Number of faces 272254 Total area 88745.070312 GroupSurface 0 FIX_VERTEX_AREA 1 AvgVtxArea 0.651919 AvgVtxDist 0.883205 StdVtxDist 0.255280 Polynomial detrending, order = 0 Computing spatial AR1 ERROR: MRISar1: Surf/Src dimension mismatch. Segmentation fault

All of the unpacking, reconstruction, and preprocessing up till that point have all been done using a pretty typical FS stream (with the exception of not smoothing in the volume) using FS 4.0.5.

The segfault happens with both the mris_fwhm binary that comes with FS 4.0.5 and with the one I built from last night's CVS tree. I haven't run it under a debugger yet but was wondering if this has been seen before, etc.
