Dear Martin,

Use the --saveVertices option (as --saveVertices=myfilename) in first_utils when you run the vertex analysis and it will save the vertex data that is used in the vertex analysis in a simple text matrix.  You can then feed this into whatever other classification or analysis method you'd like.

All the best,
	Mark

Now what I'd like to do is use classifier algorithms to take individual meshes and categorize them (e.g., Patient v Non-patient, etc..). Intuitively I'd try to use the .bvar files that get concatenated to run FIRST. However I can't quite "open" them and look into them (e.g., getting one value per vertex), so I'm not sure how I could export the values to some matrix (e.g., in Matlab). Is there a way to get individual vertices numbers (per each subject) so that I can export them and play with them?
