Hi Darren,

it is r,g,b stuffed into a 32 bit quantity:

annotation = r+(g << 8)+(b << 16)

cheers, Bruce

Hi Bruce,

it seems to work. What are the values in the vector returned?

Best, Darren

Hi Darren,

try the matlab script I've attached. It worked at one point in time, and there's a possibility that it still does :).

Let me know if it doesn't and I'll email you the c code that does.

cheers, Bruce

Dear Bruce,

can we read the parcellation annotation file into matlab?

Essentially, how can we obtain a list of all the vertex indices and their classification?

Best, Darren

function [annots] = read_annotation(fname)

% % [annots] = read_annotation(fname) % reads a binary annotation file into a vector %

% open it as a big-endian file fid = fopen(fname, 'rb', 'b') ; if (fid < 0) str = sprintf('could not open annotation file %s.', fname) ; error(str) ; end vnum = fread(fid, 1, 'int32') ; tmp = fread(fid, vnum*2, 'int') ; annots = tmp(2:2:vnum*2) ; fclose(fid) ;
