Hi Pedro, Have a look at this article: http://brainder.org/2011/07/05/freesurfer-brains-in-arbitrary-colours I think this is the same you'd like to do (or you can change some steps easily). Hope it helps! All the best, Anderson On 05/07/12 20:44, Pedro Paulo de Magalhães Oliveira Junior wr

[Freesurfer] overlapping labels

2012-07-05 Thread David Grayson
Hi freesurfers, Can a .annot file include labels with overlapping vertices? If not, then when using mris_label2annot, how does freesurfer decide which label to assign the vertices to? Thanks, David ___ Freesurfer mailing list Freesurfer@nmr.mgh.harva

Hi Pedro Paulo, it is not quite the right procedure, but I'm surprised that it gave unknown for all labels. Try modifying the colortable.txt such that the first entry is the name and color for your first label, etc. doug On 07/05/2012 03:44 PM, Pedro Paulo de Magalhães Oliveira Junior wrote: > D

You can also break up the annot into labels ( mri_annotation2label) then recombine them with a new color table with mris_label2annot. doug On 07/05/2012 02:57 PM, Bruce Fischl wrote: > Hi PPJ, > > I think the color lut is embedded in the aparc.annot. If you want to > change it you have to change

Hi PPJ, I think the color lut is embedded in the aparc.annot. If you want to change it you have to change the one that's in the .annot. I would do it in matlab. cheers Bruce On Thu, 5 Jul 2012, Pedro Paulo de Magalhães Oliveira Junior wrote: I'm trying to generate an image to a paper and
