Hi Yujing,


Thanks for the response. 


We addressed the issues by modifying the labels of the vertices that represent specific areas. To do this, we employed the 'write_annotation' function in FS (MATLAB-based). 
Anyway, It's worth noting that the PALS_B12 annotation files in FreeSurfer may require further refinement. 

Best,
Xinjie

Sorry, I take my suggestion back. Annotation values are saved in .annot file, not the label id. Different colortable won’t work.

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 MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/PALS_B12

 

Maybe a different colortable will help the visualization?

 

Best,

 

Yujing

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
