I think my last email didn't get through. Bruce, I've uploaded the 001.mgz. It should arrive in your mailbox. I can upload it again if there was any problem.
Thanks,
Anil.

Bruce, I had uploaded the orig.mgz for Nick. I think you should find
the
link below. I can also upload the 001.mgz for you. There are no dicoms because the scan is from a GE scanner (120 slices,
details are below)and all the files are named as I.??? I could also upload these files for you.
Anil.

I think it's something afni is doing, but I'm not sure. Did you give
us
the data before conversion (either the dicoms or the 001.mgz)

Hey Freesurfers,
I fed freesurfer the brainmask.mgz generated by AFNI. autorecon2
and
autorecon3 ran fine with no errors but the resulting surfaces are
not
very
accurate.
Bruce, you mentioned that my background values were too high. Is
there a
way
to reduce them so that freesurfer can do the watershed without any
glitches.
Thanks,
Anil.
