Dear list,
I have a problems running FSL on Fedora Core 2 and Debian (sarge) boxes.
In both cases I'm trying to run the precompiled RH9 binaries
(compilation from source causes problems for flame and mcflirt, will
post details later).
I have a simple 16-minute dataset (block design) and 4 EVs. Everything
runs smoothly through prestats (including MELODIC), and seems to pass
through stats too. However, the first stage of post-stats, contrast_mgr,
causes a segfault :
In FSL 3.2b:
84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,Completed
Saving results...
/usr/local/fsl/bin/contrast_mgr -f design.fts stats design.con
** ERROR: nifti_image_read(stats/sigmasquareds): can't open header file
** ERROR: nifti_image_open(stats/sigmasquareds): bad header info
Error: failed to open file stats/sigmasquareds
Error:: FslGetDim: Null pointer passed for FSLIO
In FSL 3.1:
84,85,86,87,88,89,90,91,92,93,94,95,96,97,98,99,Completed

/usr/local/fsl/bin/contrast_mgr -f design.fts stats design.con
AvwOpen: Error while opening header!: No such file or directory
The file stats/sigmasquareds doesn't exist and I can't figure out why. I
don't think it's a memory issue, as has been discussed recently, since
the nii.gz is only 65 MB. At some stage of the analysis I get two
massive core dumps
-rw------- 1 cjb petadm 316022784 Dec 2 15:50 core.25436
-rw------- 1 cjb petadm 794587136 Dec 2 15:54 core.27381
I've placed the .feat directory (minus the core dumps) tar.gzipped on
www.pet.au.dk/~cjb/FSL
(btw, it's SE data...) If anyone has time to check it out, I'd be
grateful!
Best,
Chris
