Hi Tina
how did you create it? If the vertex indices are -1 it means they are not
assigned, and when you load it into tksurfer it will sample them onto the
surface. You can then save it it will write the new vertex numbers into the
label file.
Not sure about the offset though.

Hello Freesurfers,
I have created labeling files from a subject using the area file (previously
named base). The label file corresponds to the freesurfer generated
cortical label, ctx-rh-bankssts, which I have attached in this email. The
labeling files should be the same, however, there are some discrepancies in
the files:
1). There is a slight offset in the vertices.
2). A reduced number of vertices in the .label file created from the area
file.
3). The vertex numbers are numbered -1.
Our goal is to overlay a custom atlas onto a cortical surface generated from
amira in freesurfer. Can you please tell how to transform the labeling files
so that I can successfully overlay them?
I have attached all three files for you. rh.rh_label_2001.label is the
labeling file created from the base file, rh.ctx-rh-bankssts.label is the
label from freesurfer and the rh.base file I have sent to Bruce the file is
too large. When I overlay the rh.rh_label_2001.label and other labels
generated from the base file, only parts of the temporal lobe are overlayed.
Thank you in advance,
Tina Jeon
