Re: [Freesurfer] cluster/peak vertex infomation

1. What is the easiest way to obtain peak vertex information from a given cluster?

2. For a given sig.mgh file, is there a command which outputs a list/text file of all clusters present?

Hi,

The --sum option allows you to provide a name for the textfile it will generate containing information about each cluster. In the text file, each row will have a MaxVert field.

mri_surfcluster ... --src <inputfile>.mgh --sum <sumfilename>.sum

3. Is there a way to restrict the clusters displayed in the sig.mgh file to clusters of a given # of vertices or larger?
