Dear Freesurfer experts,
I've calculated a
I used the mri_glmfit for a one-sample group means (osgm) analysis:
mri_glmfit --y Tatool_lh_thickness.15.mgh --fsgd FSGD.txt --glmdir Tatool_Thickness_LH.glmdir --surf average lh --osgm --cortex
with following FSGD file:
GroupDescriptorFile 1 Title Tatool working_memory_group_young

In a second step, I tried to correct for mulitple comparisons by using the glmfit_sim:
mri_glmfit-sim --glmdir Tatool_Thickness_LH.glmdir --sim mc-z 5000 1.3 lh_mc-z.abs --sim-sign abs --overwrite
But there was the following errormessage:
ERROR: dimension mismatch between y and X. y has 16 inputs, X has 32 rows.
Has anybody solved this problem before?
(When I delete 16 rows of the FSGD file the simulation works, but then I don't trust the output anymore)
Thanks for your help.
Best,
Nicolas
