Hi,
I would like to run a group analysis on the 4Dresiduals (i.e., res4d.nii.gz ) from the lower-level analysis. As suggested elsewhere in the archives, I have added a value of 100 to the brain voxels, because the mean of the residuals is 0 and FEAT won't work if one feeds in zero-mean data.
Once I run the analysis with the new res4d file, I always get the same error message in the „Higher-level input files preparation“-Log:
/usr/share/fsl/4.1/bin/fslmaths mean_func -Tmean mean_func
syntax error in expression "1 + res4d_new": variable references require preceding $
while executing
"expr 1 + $copenumber "
(procedure "feat5:proc_gfeatprep" line 267)
invoked from within

(file "/usr/share/fsl/4.1/bin/feat" line 137)
I would be very grateful for any help or suggestions.
Thanks,
Goran
