Hi Doug, I finished recently running FSFAST on fmri data set. I want to run group GLM for the following analysis:
OSGM, FSGD( no covariates) For OSGM I ran the following command line like in Wiki: mri_glmfit --y ces.nii.gz --wls cesvar.nii.gz --osgm --surface fsaverage lh --glmdir my-glm.wls --nii.gz then mri_glmfit-sim --glmdir my-glm.wls --cache 3 pos --cwpvalthresh .0166 And as a result I got the output "cache.th30.pos.sig.cluster.summary" I tried to run the same previous command lines for the second analysis (FSGD( no covariates)) by adding the suitable fsgd and the contrast flags as the following mri_glmfit --y ces.nii.gz --wls cesvar.nii.gz --fsgd fsgd --C C1.mtx --C C2.mtx --C C3.mtx --C C4.mtx --surface fsaverage lh --glmdir my-glm.wls --nii.gz I got the following error "MatrixMultiply: m2 is null!" I tried to run the previous command line without the flag --wls as the following: mri_glmfit --y ces.nii.gz --fsgd fsgd --C C1.mtx --C C2.mtx --C C3.mtx --C C4.mtx --surface fsaverage lh --glmdir my-glm.wls --nii.gz And the analysis ran smoothly. My Question is. Why this flag gave me the error message. What is the meaning of this message and what is this flag standing for?
