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.

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

Thank you, Bruce, as always. The BA_exvivo.thresh.annot does not annotate all the vertices, see attached BA.png. Is there a complete Brodmann map like in the atlas image? Thank you, Octavian

Hi Octavian

 

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

 

Cheers

Bruce

Dear All, 

 

These are probably rookie questions. 

1. 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. 

 

2. On the same line, how one combines all the Brodmann labels into a Brodmann parcellation, if not done already..

Thank you, 

Octavian
