Hi,
Are you running this on a linux machine?
There appears to be a problem with FLIRT compiled on Redhat 8 and 9. If
you are getting segmentation faults when running flirt, then download
the non-optimised version from
www.fmrib.ox.ac.uk/fsldownloads/flirt_noopt
<http://www.fmrib.ox.ac.uk/fsldownloads/flirt_noopt> which, although it
runs slower, should not crash. In the unlikely event that it still
crashes, please post the details on the FSL email list.
To install this version of flirt do the following:
1 - download the file from the website (as flirt_noopt)
2 - mv $FSLDIR/bin/flirt $FSLDIR/bin/flirtopt
3 - mv flirt_noopt $FSLDIR/bin/flirt
4 - chmod a+x $FSLDIR/bin/flirt
You may need an administrator to do the last 3 steps, depending
on whether you have permission to write to $FSLDIR or not.
All the best,
Mark
