Dear All, I wonder if some kind soul could help us out a bit here: I just downloaded the Redhat9 version of FSL. Un-tarred it, added the fsl/bin to my path and created $FSLDIR. When I typed fsl, it said segmentation fault. So I also tried the fixes recommended for Suse (although ours is a Redhat9). It now says: afraim@mandrake:/home/afraim<132> fsl Error in startup script: couldn't load file "/home/afraim/fsl/lib/libtix4.1.8.0.a": /home/afraim/fsl/lib/libtix4.1.8.0.a.so: cannot open shared object file: No such file or directory while executing "load /home/afraim/fsl/lib/libtix4.1.8.0.a Tix" ("package ifneeded" script) invoked from within "package require Tix" (file "/home/afraim/fsl/tcl/fslstart.tcl" line 2) invoked from within "source [ file dirname [ info script ] ]/fslstart.tcl" (file "/home/afraim/fsl/tcl/fsl.tcl" line 11) invoked from within "source ${FSLDIR}/tcl/${origname}.tcl" (file "/home/afraim/fsl/bin/fsl" line 29) I guess this is better than 'segmentaion fault', but still not ideal. I just had a look in fsl/lib and there is no such file called libtix4.1.8.0.a Is there supposed to be?
