External Email - Use Caution Dear Freesurfer experts, I have what seems like a simple problem, and I'm sure there is a method for doing this, hoping someone can give me some guidance. We have results from an LME model run on surface data, and then run through PALM to calculate FWE-corrected p-values from the LME. We now would like to extract the mean beta values from each anatomical label region, within regions that were significant at p-corrected < 0.05. The beta values (as well as the PALM p-values) are contained in an mgz surface file. So, what I think is needed is: 1) Create mask images for each individual label index, e.g. lh.caudalmiddlefrontal 2) Create mask image from PALM results, for p < 0.05 3) Multiply mask * label * beta, and calculate mean value in that region So, my simple question is what are the appropriate FS commands for performing this (or alternatively Matlab commands), or is there a simpler way or extracting these values? Thanks for any advice you can give us on this.
