Hello All,

I havent used dt-recon yet but I have a question abt it.

When the dt-recon computes the FA maps, whats the dimensions of these FA maps ? Are they resampled to the freesurfer anatomical voxel size (1x1x1) or are they in their native voxel size (in which they were collected) ? If I want to extract say the meanFA from one of the ROIs that freesurfer dumps in aseg/wmparc, can I do that ?

Thanks
