thanks Dr. Fischl - it seems to match well so I will continue to use this method. It would be great if Ruopeng could eventually edit Freesurfer to allow for thresholding .labels too.

On another note, is there a way to edit labels in Freeview in a similar manner to doing so in tksurfer? From what I can tell, one can only edit volume segmentations in Freeview.

yes, that sounds right. Does it look correct? That is, are areas 1/4 etc.. in the central sulcus and such?

Not a problem, Dr. Fischl!
In the meantime, could you please confirm that I am opening up a cytoarchitectonic probability map I have as .mnc
correctly? 

I basically change it to a surface overlay.mgz using mri_vol2surf and then open it as an overlay with a surface in
Freeview. I can then change the thresholds using "configure overlay".

            Hi there

            With regards to this email from March, I cannot seem to be able to change
            thresholds of .labels in Freeview. Could this be added as an option?

            best wishes

                  Hi Trisanna

                  1. the .thresh labels have been thresholded with a p-value
                  threshold that is "best" on our training set of
                  manually/architectonically defined labels.

                  2. Hmmm, not sure, but we have stopped development on tksurfer.
                  Can you try this on freeview? I can't remember if freeview
                  allows changing thresholds in labels, but if not Ruopeng can add
                  it to his list of feature requests

                  cheers

                        Hi there
                        I have two questions regarding using the labels with
                        tksurfer:

                        1. What exactly has been done to change the .label
                        (e.g. lh BA44.label) to
                        .thresh.label (e.g. lh BA44.thresh.label?

                        2. The instructions on this page 

                        https://surfer.nmr.mgh.harvard.edu/fswiki/BrodmannAreaMaps

                        to overlay the labels and set the Min and Max do not
                        seem to work for me - I
                        cannot seem to alter the Min from 2 and the Max from
                        5. Any thoughts as to
                        why?

                        thanks very much!
