Hello,
I want to do a FDR correction using mri_fdr within a ROI mask (in .label format). I see the option of passing the sig.mgh volume through a mask, and I read that one can use the mask.mgh in the GLMFIT folder. What is this mask.mgh? I tried to visualize it in Freeview but it doesn’t look like a mask but rather some sort of geometric form. If I have labels as my ROI, how do I convert that into a .mgh format to be used in mri_fdr? (I tried simply using the label file first and obviously that didn’t work…)
Thank you in advance,
Jeni Chen
Is this a volume or surface-based analysis? How did you try to visualize it?
