Hi Freesurfers,
I have some participants of whom I obtained retinotopic polar angle data in
a previous session, and scanned eccentricity data in a later session. I
used the polar angle data to define V1-3, and would like to display these
labels on the eccentricity session to help me define V3A.
However, when I load my old V1-3 labels onto the inflated brain based on
the new session the labels look very strange. I attached a screenshot of
what is supposed to be lh dorsal V1, as you can see it is scattered all
over the cortex. When I load the .nii based on the label into MRIcron, the
ROI looks fine.
Data from the newer session were coregistered to the older session, so that
can't be the problem.
I looked around on the wiki and found the command mri_label2label that
seemed useful. However, this command needs acces to the 'surf' folders of
both sessions. Due to a computer crash I only have the labels of the
previous session, not the 'surf' folder. Is there a way to display my old
labels onto the new session without needing access to 'surf'?
Thanks,
Bianca
