Dear FSL users,
I've recently completed a MELODIC analysis across three separate groups (total N = 48) with the intention to use the resultant maps (as matched according to the Beckmann RSN8 nii file with fslcc) as a guide for selection of regions for a higher-level analysis. There are a few questions, however, that I needed a little guidance on:
-- Given ICA maps cover quite a large area, I was wondering if there was a way to choose peak voxels of a given map (say, executive control) for subsequent analyses (e.g. DCM)? Would Featquery or FSLView be useful here? Would it be best to first choose peak voxels from the group-wise maps (e.g. melodic_IC.nii.gz) and then select voxels from each individual map (which I assume are the files named "filtered_func_data.nii.gz") using a function such as fslmeants?
Any help would be greatly appreciated!
Cheers,
Matt
