Hi Leila,
it will set the global variable named "select" after the call to
select_talairach_point x1 y1 z1. You can then use it (with $select)
afterwards.
cheers,
Bruce

Hello,
Thanks Bruce,
Super, it works well!
I tried to make my rois in a script (to do it in many subjects), by using the
commands:
select_talairach_point x1 y1 z1
select_orig_vertex_coordinates
mark_vertex
path_new_path_from_marked_vertices
but I did not manage to get the vertex number (index), I only can get the
coordinate, and I cannot use them to mark the vertex and make the path.
Is there any solution?
Thanks again
Leila

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.
cheers,
Bruce

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
