hi all
         i run recon_all on some subjects having 512x512x154 , i noticed
(using tkmedit) that there are no problems with orig.mgz, and rawavg.mgz but
most of them were cropped (more than half of the brain disappeared) after
the "-nuintensity" step (nu.mgz); for one of these patients, the nu.mgz is
ok but the T1.mgz produced after skullstrip is bad : the skull was largely
still there on the right hemisphere.

   i read in the "recon-all.local-copy" file (in the
SUBJECTS_DIR/subj/scripts folder) that we must include the "-cw256" flag if
the "FOV" is beyond 256x256x256 (just to be sure, is it the FOV -in mm- or
the just the GRID). but when reading in the recon-all.log file, this step
seems to be a default one when running "recon_all -all" command. in the
recon-all.log file it is written :

Original Data has (0.4883, 0.4883, 1.2) mm size and (512, 494, 154) voxels.
Data is conformed to 1 mm size and 256 voxels for all directions
changing data type from float to uchar (noscale = 0)...
MRIchangeType: Building histogram
Reslicing using trilinear interpolation

thank you for your help
