Hi Bruce,
 
Yes, mri_info works on all these files, and it states that it's an mgh file and the dimensions look allright and it says: type FLOAT (3).
 
Here's the output for the left hemisphere (with command line)
 
[lmr@localhost area]$ mri_surf2surf --s fsaverage --sval
/home/lmr/subjects/analysis/TOP_sm100_lh_cc2_11072009.mgh
--hemi lh --fwhm 30 --tval
/home/lmr/subjects/analysis/TOP_sm100.s30_lh_cc2_11072009.mgh
 
srcsubject = fsaverage
srcval =
/home/lmr/subjects/analysis/TOP_sm100_lh_cc2_11072009.mgh
srctype =
trgsubject = fsaverage
trgval =
/home/lmr/subjects/analysis/TOP_sm100.s30_lh_cc2_11072009.mgh
trgtype =
surfreg = sphere.reg
srchemi = lh
trghemi = lh
frame = 0
fwhm-in = 0
fwhm-out = 30
label-src = (null)
label-trg = (null)
