Hi, Freesurfers. I need to create some labels from binary masks. Sometime ago I read a post (https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2013-October/033783.h... ) and, unless I am wrong, it seemed to me that mri_label2vol could be the tool to get it. If so, could you please explain how? I read documentation on wiki and help from the command itself and could not see how to accomplish that. I could only find how to create a volume from a label. What I need to do is to get a mask like the binLeftHippoHead.mgz (attached) and create a label. Assuming it is possible, I could also make labels for Hippocampal body and head, merge the 3 labels into an annot file. This way i can use Freeview to load the whole hippocampal surface and discriminate the 3 segments by colors with the annot file. Thanks in advance for any help. Cheers, Marcos.
