Can you check the modification time of ~/audio/all/audio.lh/tones/ces.nii.gz ? Try deleting it and rerunning isxconcat-sess. The only other thing that I can think of is that some of the individual ces files have multiple frames. You can check that with mri_info --nframes */bold/audio.lh/tones/ces.nii.gz If the problem persists, send the terminal output of isxconcat-sess

Hi Freesurfer experts
I'm having a problem running an FSFAST group analysis. When I try to run the second level GLM, I get the following error:

108 is the number of subjects that I have. I can see that the y file with 116 inputs is /home/keri/audio/all/audio.lh/tones/ces.nii.gz , and checking the dimension of it, it confirms that it is a 4D matrix with the 4th dimension of 116. It seems as if this file is created during isxoconcat-sess, and I have checked and the session ID file being used here has only 108 entries. It appears that 108 subjects are being used in this step, as part of the output is:
ninputs = 108 Checking inputs nframestot = 108 Allocing output Done allocing nframes = 108
I think that a source of the error could be the fact that at one time I did have 116 subjects. I've created a new folder, copying in the unpacked files for each subject, and repeating from the preprocessing step, but this doesn't make any difference. Is there are chance that there's a file outside the functional directory that has stored this 116?
Any help is greatly appreciated.
Best wishes, Keri
