Hi FSL experts,
I am trying to run a 2 (group, between sub) x3 (condition, within sub) mixed effects model using flameo command. I am using the FLameo command instead of Feat GUI because the gui freezes when I attempt to add a lot of regressors (e.g. add a regressor for each subject).
However, the output I am getting is retuning (a) an empty mask and (b) empty t-stats files. I do not understand why this is happening, because I am 100% sure (and re-tested 3 times) that the mask.nii.gz, cope files, and varcope files that I am feeding into the flameo command have the entire brain covered. I have copes and var copes for each condition for each subject, and I asm using the mask that was generated from a previous group-level analysis with the same set of subjects. My varcope file, cope file each have 219 volumes (73 subs x 3 conditions), and my design files reflect that.
Here is the flameo command:
flameo --cope=all_copes_angry_happy_neutral --varcope=all_varcopes_angry_happy_neutral --mask=mask.nii.gz --dm=design.mat --tc=design.con --cs=design.grp --runmode=flame1
I have also attached my design files.
Thanks,
Michelle
