Dear FS experts,
I am looking at the relationship between the cortical thickness and a behaviour measure, while controlling for the effects of age and gender. In this analysis, I am using CT_AT.fsgd, contrast_pos.txt and a contrast_neg.txt.
GroupDescriptorFile 1 Title Autistictraits Class AT Variables Age Gender AT
Input Con_P001 AT -4.142 -0.428 21 Input Con_P002 AT -8.142 -0.428 31
My separate two contrast files:
Contrast_pos.txt 0 0 0 1
Contrast_neg.txt 0 0 0 -1
mri_glmfit --y lh.thickness.AT.10B.mgh --fsgd CT91_4.fsgd doss --C Contrast91_pos.txt --surf fsaverage lh --cortex --glmdir glmdirlhposlat.glmdir
mri_glmfit --y lh.thickness.AT.10B.mgh --fsgd CT91_4.fsgd doss --C Contrast91_neg.txt --surf fsaverage lh --cortex --glmdir glmdirlhneglat.glmdir
mri_glmfit-sim --glmdir glmdirlhposlat.glmdir --cache 1.3 pos --cwp 0.05
mri_glmfit-sim --glmdir glmdirlhneglat.glmdir --cache 1.3 neg --cwp 0.05
By changing the commands appropriately, I am looking at the right hemisphere too.
Can anyone please help me to clarify, if I am applying the command lines correctly? Any sort of help would be very much appreciated. Thanks !
