Hi Freesurfer experts, I want creat some ROI masks or parcellation from Caret PALS_B12_Visuotopic.annot file in fsaverage's label folder.
I used the command mri_label2vol, mri_label2vol --annot $Dir/label/lh.PALS_B12_Visuotopic.annot --temp $Dir/mri/T1.nii --fillthresh .5 --o PALS_B12_Visuotopic.nii --subject fsaverage --hemi lh --identity The parcellation in output volume were like some lines located at the boundry of white matter , and did not cover the gray matter (see picture).
Then, I used another methods as follows. Firstly, I converted the annotation file into some label files using mri_annotation2label command; Secondly, I created ROIs using these labels by mri_vol2roi. However, the masks also couldn't cover the gray matter.
Could anyone help me creat good masks? Thanks a lot!
