-- This is really getting crazy.  We are all trying this – various OS flavors have different responses.

 

==============================

From Clark (using Ubuntu 9.04 -- recent OS build)

Christian:

 

fsl_tsplot –I f1.txt –o tst1.p;ng –t “test title” –a lab1,lab2 –x XAxis –y YAxis

 

works fine

 

fsl_histogram –I mean.nii.gz –o tstHisto.png

 

generates a Segmentation Fault.

 

 

==============================

From Natalia:  (Using A RedHat flavor)

Looks like the histogram work fine, but I am unable to get tsplot to work.

 

here is my command line: fsl_tsplot –i f1.txt,f2.txt –o RH_tsplot_tst1.png –t “RH test title” -a lab1,lab2 –x XAxis –y YAxis

 

error message:

***************************************************

The following COMPULSORY options have not been set:

         -i,--in         comma-separated list of input file names (ASCII text matrix, one column per timecourse)

         -o,--out        output filename for the PNG file

***************************************************

 

weird. I've tried several times.

 

By the way, I looked at my old group melodic reports that failed, and I did not get a segmentation error like you did - mine just quits with no feedback at all.

Hi Clark,

 

FYI.  When I run the fsl_histogram command (e.g. fsl_histogram -i mean.nii.gz -o tstHisto.png), I do not get a segmentation fault.  This is true both when I run the command on the VM (FSL version 4.1.5) and on the workstation (FSL version 4.1.4).  (Note too that the output (histogram image) looks reasonable.)

 

Best,

Sonya

Thanks Clark, very useful, this narrows it down quite a bit...

Hi Clark,

 

Can you try running fsl_histogram and fsl_tsplot with titles/labels - I suspect some 3rd party low-level library used for adding text to images is causing the problem. If it is possible for you to provide a guest account on your system that would be very helpful

Thanks

Christian

Hi:

 

We are having trouble with Melodic – it won’t write the report.  We are running 64 bit Ubuntu 9.04 and a Redhat (not sure of the version).  We are fully patched.  The run associated with the attached files was just a “lets see what happens” with only 4 subjects – it runs pretty much as expected until the report and then exits with a segmentation fault.

 

I know it is possible do idiotic things with the Melodic interface (e.g. request background image be set to Mean High Res but not provide any subject Hi-res images) so it may be something stupid we are doing – Still, it seems like the 64 bit version (in particular) is a bit buggy and we are wondering if this is something that needs a little attention;
