Dear Doug, Thanks for getting back and for your patience. I see. mri_label2label does something much fancier and more precise than simply using a linear transformation to get from one to the other. It definitely works as the transformed vectors of a label from several subjects plot right on top

Hi, In freeview, when I load a volume the voxels are not square to the viewing windows. Is there an option to view the data with the voxels square to the viewing windows? Thanks, Dan ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mai

Ok! Can I still use these masks as long as I know what areas are interpretable? If so, what does it mean in terms of my original question (limiting the MCS to subcortical structures)? From: freesurfer-boun...@nmr.mgh.harvard.edu [freesurfer-boun...@nmr.

It does not discredit your results. This is not unexpected behavior. As you change cluster forming thresholds, the clusters will change sizes, but the null distribution will also change in complicated ways. The end result is that it is not easy to predict the effect on the number and sig of yo

Dear List, Sorry to be unclear in my questions. I had a fundamental misunderstanding which I hope to rectify. (1) It appears that what is called the "freesurfer" coordinate system (tkregister) is represented by subject fsaverage. 3D coordinate vectors in label files generated for any subject
