Hi Xinjie,
?h.PALS_B12.labels.gii in fsaverage/label/ seem to have duplicated color
schemes assigned to the labels you mentioned. I'm assuming
?h.PALS_B12_Brodmann.annot is generated from the GIFTI
https://surfer.nmr.mgh.harvard.edu/fswiki/PALS_B12
Maybe a different colortable will help the visualization?
Best,
Yujing

Subject: [Freesurfer] Issue with PALS_B12_Brodmann.annot Labels in FreeSurfer
External Email - Use Caution
Dear FreeSurfer Team,
I am writing to report a significant issue I have encountered while using the
PALS_B12_Brodmann.annot files in FreeSurfer. I have noticed a critical error
concerning labeling certain Brodmann areas.
Specifically, in the left hemisphere, labels such as Brodmann area 33,
CON_deeper_than_WS_t_2', and ASP deeper' appear to share the same label ID.
Similarly, in the right hemisphere, the label for Brodmann area 3 seems to be
merged with Brodmann area 33. This overlap of labels and the lack of unique IDs
for distinct Brodmann areas like Brodmann 3 and Brodmann 33 are causing
significant confusion and potential errors in analysis. For instance, this
issue complicates tasks such as calculating variables for individual Brodmann
areas, leading to inaccurate results.
I am keenly interested in any solutions or methods you could suggest for
resolving this problem. Thank you in advance for your assistance and I am
looking forward to a resolution.
Best regards,
Xinjie
