Hi all,

after running a group comparison using qdec I wanted to use mc-z instead of FDR for multiple comparison correction

I tried to run mri_glmfit-sim-mc-z.abs.2

and got an error...

ERROR: dimension mismatch between X and contrast /Users/..../subjects/qdec/Untitled/tmp.mri_glmfit-sim-5637/lh-Avg-Intercept-area.pial.mtx

X has 8 cols, C has 4 cols

what does this mean and how to fix it?

thanks, Mark
