Hi Paul
Have you run recon-all on your data? If so, then there will be .annot files that you can use to look up what parcellation unit is at that coordinate in any given subject. Or closest to that coordinate as in general it may not be in the cortex

External Email - Use Caution
Dear FS community,
My ultimate goal is to do a seed of interest connectivity analysis. Accordingly, I have MNI coordinates for a seed (e.g., left DLPFC). However, for the softwares I am using (CONN toolbox and Brainstorm), I need a .annot file which has the surface region of interest label I want to use as the seed.
My problem is I do not know how to create an .annot file from MNI coordinates of my seed/region of interest.
Can I create an .annot or label file with Freesurfer centered around an MNI coordinate, or would I first need to create a volume ROI using another software?
Any directions as to how I can do this would be greatly appreciated.
Best Wishes, Paul
