Hi Doug, I am working on a GLM for functional connectivity analysis. I made simple FSGD file for two groups + NO covariates then I ran the following command line on the right hemisphere and the left hemisphere.
mri_glmfit --y ces.nii.gz --wls cesvar.nii.gz --fsgd fsgd --C Contrast1group.diff.mtx --C Contrast2group1.mtx --C Contrast3group2.mtx --C Contrast4g1g2.intercept.mtx --surface fsaverage lh --glmdir glm-fsgd-2G0C.wls --nii.gz On the right hemisphere the output is fine for all the contrasts. On the left hemisphere and after writing the results for contrast 1 I am receiving the following message: MatrixMultiply: m2 is null! Kindly what is the meaning of this message? Thanks, Mohamad _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
