Thank you, Bruce. Just to exhaust the annot issue. I assume that the labels (parcel names) are not embedded in .annot or aparc+aseg.mgz per se, but they are read from the LUT table by matching annot vertex indices to col 1 in the LUT. Is there any .m file that can do that? If not, I can write one, but wanted to check, thank you. Octavian

Alas there is not – there are large parts of the cortex that have not yet been mapped for microstructural boundaries

Hi Octavian
- Yes, there is a write_annotation.m that you can use.
- We output an annot of the max probability labels at each point I
think called BA_exvivo.thresh.annot
Cheers

External Email - Use Caution *Dear All,
These are probably rookie questions.
- I can read an .annot file with read_annotation.m, is there a way to
write one? (for example read it to matlab, modify, and save, or create a combined (lh+rh) aparc.annot file etc.
- On the same line, how one combines all the Brodmann labels into a
Brodmann parcellation, if not done already..
Thank you,
Octavian
