Hi I just find out how to launch the command, it is in the terminal where tksurfer is running, after the % sign. (I didn't understand what the tcl window was meaning) Best Celine
Hi I am sorry if my question is really basic, but I am choosing the seeds for fsfast resting state connectivity analysis, and I am looking at the different options in the litterature. Seeds are often presented with the talairach coordinates, and I was looking for a way to find the corresponding vertex number on fsaverage surface, so that I can build the corresponding label that I could use for the fcseed-sess command. I found this previous email, and there seem to be a command to do that but I don't know how to launch this command select_talairach_point <xtal> <ytal> <ztal> Thank you very much Celine

Hi Leila,
you can use the tcl command
select_talairach_point <xtal> <ytal> <ztal>
in tksurfer in the tcl window (with the % prompt), then make a label from that point and dilate it a few times.

Dear Freesurfer users and experts, This is my second attempt :( I am trying to construct a roi based on some talairach coordinate
coming from a paper, but I completely fail to do it with matlab and neither manually with tksurfer.
My first try was to use the transformation Talairach.xfm with matlab,
inverse it and try to recover RAS coordinate, it gives me completely wrong values.
Second try was to introduce the Tal coordinate directly in Tksurfer,
which is not possible I think (correct me if I am wrong), with the version I have the is a bug in tkmedit I guess when introducing Talairach coord (the ideas was to save them and to load the vertex in tksurfer).. the values changes in the edit box..
Is there another way?? Is it possible with script? Or how to do this by matlab? Please don't ignore the request. Leila
