Dear List,
I'm having a problem processing data from multiple subjects. On the 2nd level analysis where
multiple runs of each subject were processed went fine. However, on the 3rd level where multiple
subjects are processed, I got the following error message in the terminal window:
couldn't open "tmpreport.html": no such file or directory
while executing
"open tmpreport.html r "
(procedure "feat5:report_insert_stop" line 4)
invoked from within
"feat5:report_insert_stop poststatspics"
(procedure "feat5:poststats" line 348)
invoked from within
"feat5:poststats 0 [ expr $fmri(level) - 1 ]"
(procedure "feat5:proc" line 1362)
invoked from within
"feat5:proc [ file rootname [ lindex $argv 0 ] ]"
(file "/usr/local/fsl/bin/feat" line 16)
In the report.log (1st one in the attachment), I saw the following error:
/usr/local/fsl/bin/avwmaths mask -Tmin mask
** ERROR: nifti_image_read(mask): can't open header file
** ERROR: nifti_image_open(mask): bad header info
Error: failed to open file mask
Error:: FslGetIntensityScaling: Null pointer passed for FSLIO
It seemed that the mask.nii.gz was not created by the avwmerge command just before the
avwmaths command, so I tried running the avwmerge command by itself in the terminal and got
“segmentation fault.”
Is it this “segmentation fault” that is failing the 3rd level analysis? What does it mean? From
reading some of the earlier postings, I understand that segmentation fault occurs when you try to
convert large 3d data to 4d, but the masks that the above avwmerge command is trying to
concatinate are pretty small (~21KB). I also checked the dimensions of the masks, and they are all
the same.
I’d appreciate any help you could give me!
(I tried to post the above message in reply to an earlier posting, but it didn't seem to go through. I
apologize if you have read my earlier message.)
