External Email - Use Caution Hi Experts,
I wonder if anyone can give me any advice on a couple of things. 1) I have some ICA spatial maps which I have resampled to the surface using bbregister and vol2surf. I can load this data in Freeview as a generic overlay (see attched). I also have a label file which is a combination of several visual areas. What I want to do is use this label as a mask and remove any activation from the ICA map overlay which falls outside of the label/mask. Is this possible using Freesurfer? In FSL I have been using fslmaths with -mas flag. 2) My next question is whether it is possible to run spatial correlations on the surface. For example, I would like to know how well my ICA component maps match with some visual areas labels I have created in Freesurfer. In FSL i have been using fslcc to run these correlations between my ROIs and the spatial maps in the volume.
