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.
What form are your labels in? If they are just binary masks, then you
can use mri_mask
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.
You want to compute a correlation coefficient? Or a dice score?
Thanks in advance,
Mason
