I wrote the code in matlab, and it works ok. My code is available at: http://www.nmr.mgh.harvard.edu/~daniel/links/matlab/labels_to_annot.m
It isn't elegant though. The annotation file does not name each label, and the colors appear to be fairly random.
If I had more knowledge of the annotation file format, I could fix this, but nonetheless it works as is. Anyone out there with the desire to use it is free to do so.

Hi Daniel,
here's a .m file for reading in the .annot files, which should give you the format.
cheers, Bruce

Ok. Well I wouldn't mind whipping this up in matlab, but I need to know the format.

You'd also have to make sure that the labels did not overlap as there is no way to represent this in the annot file.

no, I don't think so. I guess you'd need a color file as well. It would be pretty easy....

Is there a command out there that converts a set of labels into an annot file automatically? It would be very useful...
