Hi - symbolic links are used to save a lot of disk space. For example,
every time you run registration in FEAT, it links to highres structural
images and the MNI152 rather than making a fresh copy each time. If you
use "tar" to copy a FEAT directory the link will get preserved, which may
be what you want. Altenatively if you make a temporary copy of the FEAT
directory using "cp -r" before copying that somewhere else, or backing it
up, normally by default that will replace the link with the link's target
file.
Please see previous email list postings for more on this, including
comments on replacing $FSLDIR/bin/imln with imcp to stop using links.
Cheers, Steve.
