Hi,
I'm in the stable 4 environment of FreeSurfer and am getting an error
when I try to grad_unwarp a volume that comes out of unpacksdcmdir. The
rror I get is:
gradfilename is
/autofs/space/windu_006/users/grad_unwarp_bash_MartinosCenter/grad_unwarp_tables/avanto.gwv.

Hello,
I am having trouble deciphering why I got the error attached below. Any
suggestions would be greatly appreciated!
Thanks,

Jerry,
I'm not sure why it exited without giving a better message, but this is
a clue why it exited:
before smoothing, mri peak at 0
after smoothing, mri peak at 0, scaling input intensities by inf
the mri peak is at zero, which is wrong (it should be around 116/117 or
so).
if you view nu.m
Bill,
You can try breaking apart the flash30.mgz file like this:
foreach f (0 1 2 3 4 5 6 7)
mri_convert -f $f flash30.mgz flash30_f${f}.mgz
end
and grad_unwarp each file.

Thanks for the reply, Nick. I think you correctly identified the problem.
nu.mgz is oriented correctly, but looks very dark... However, it looks
decent if I adjust the brightness/contrast
I have other scans that were processed without error, and the orig.mgz, and
nu.mgz also appear quite dark (
Jerry,
At this point, I think Bruce will need to jump-in to answer (he is out-
of-town today). I think he will ask about your scan parameters, ie, how
is your scanner setup? It sounds as if something is not quite right in
the data coming-off the scanner.

Hi
I found via google that the freesurfer is open source and wanted to download
the sources. I found one following URL
http://surfer.nmr.mgh.harvard.edu/fswiki/DevelopersGuide. The sources are
available at CVS repository which requires USERname and MACHINEname to access
them. I am wondering if
