Thank you, Nick. I tried using fixup_mni_paths, but received a poor result. I copied the stdout below:

Note: not all systems will require a patch,
and may not show any differences.
Now a test of the MNI tool 'nu_correct'...
nu_correct: Command not found.
A version number and usage message should have been displayed.

I double-checked that /usr/bin/perl exists, so that's ok. I've been crawling the forums, but I can't find a good answer for what appears to be a simple problem. Can I fix this manually? 

Thanks!

Susan,

there appear to be two problems here.  the first and main problem is the
one:

nu_correct: Command not found.

nu_correct is a script which has as its first line:

#!/usr/bin/perl -w

so can you check that you have perl installed at /usr/bin/perl?

better yet, run this script:

fixup_mni_paths

which does the checking for you and attempts to fix the scripts.

the other problem appears to be the fact that mri_nu_correct.mni doesnt
exit upon finding the error that the files are missing.  this is bad,
although in looking at the script, it ought to.   the next release will
contain a double check.  from the looks of your script, it appears that
you are running recon-all with a subject that had its data already
processed, so nu.mgz existed already, so it just used that and continued
on.  so the results are correct (assuming nu.mgz was decent to begin
with), but resolving the nu_correct issue is the important thing to do.
