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.
