Hi Bruce,

Thank you for your message. I could not locate mri_label_vals:

[hereford:maps] (nmr-std-env) mri_label_vals mri_label_vals: Command not found. [hereford:maps] (nmr-dev-env) mri_label_vals mri_label_vals: Command not found.

in either the std or the dev nmr environment. Do you happen to have the path to it?

Also, do you have something that converts a label file (e.g. containing one label) to a binary mask?

I really appreciate this.

Hi George,

there's a binary named mri_label_vals that will spit out all the values in a label. You can then compute whatever statistics you want.

cheers, Bruce

We would like to calculate the mean and std. deviation over a region of interest using tkmedit. The underlying image volume (on which the ROI is delignated) is a scalar map. Kevin mentioned that there might be a tool in the Freesurfer suite that will do that calculation.

I would really appreciate your input.
