Dear FreeSurfer experts,
I am trying to run *mri_glmfit *on a series of concatenated volumes.
mri_glmfit --y $SUBJECTS_DIR/concat/new_glm_input.mgh --fsgd Qdec/qdec.fsgd --mask fsaverage/label_volume/mask.mgz --glmdir glm_output --C $SUBJECTS_DIR/qdec/Untitled/contrasts/lh-Avg-Intercept-volume.mat
I am getting the following : WARNING: no voxels in AR1 computation. I am guessing that this is due to the results of the analysis, or is this potentially a problem with the specific contrast used? If so, what should be kept in mind while creating new contrasts?
Regards, Francesca
