Dear FSL List:
I am trying to run tica with melodic (Melodic Version 3.05). First try on my
own data failed, so I tried it on the fsl course data. Again, no success. I
tried it on different debian/ubuntu systems (e.g. ubuntu hardy, amd64bit,
4GB Ram) and get errors on all systems.
I get a "segmentation fault" error messages in logs/gica:
--snip--

In another case (another computer) I get:

How can I figure out what goes wrong and how to fix it?
Cheers,
Sascha
