Finally, to your other post above, the --fsaparc flag creates all the FreeSurfer surface segmentations, but it will not map them into the white matter, so you are right, the wmparc. readmgz. orig means lh. stats – right hemi Desikan/Killiany surface stats lh. mgz should be missing (unless you run FastSurfer with the --fsaparc where it should get created using the slower FreeSurfer approach).

To accurately map a manually drawn or pre-existing label of a region of interest to several subjects in your study, you should first register your label to or draw your label on fsaverage (a template to which all subjects run The FreeSurfer-based analysis also revealed that the majority of cerebral cortical regions accumulate amyloid in parallel, with slope of accumulation being the primary difference between regions. fs_cmd 13 External Email - Use Caution Dear experts, I am running mri_aparc2aseg using two annotations as input (one for each hemisphere), each with 159 labels, and wish to end up with a single output segmentation of 318 labels.
