Dear all,
I'm trying to read a flattened patch (ascii) using matlab but I'm
slightly confused:
after performing mris_flatten and
mris_convert -p rh.patch.flat rh.patch.flat.asc
I get the following file:
#!ascii version of patch ./rh.orig. The 1st index is not a vertex number
12755 25052
-46888 vno=46887
-47.306606 -24.583883 0.000000
-46894 vno=46893
-44.649334 -26.691339 0.000000
...
94637
48206 48190 46887
94661
48221 48205 46896
And based on the read_patch script (freesurfer_dir/matlab) I'm able to
extract the vertices and faces.
vertices_flatmap:
-47.3066 -24.5839 0
-44.6493 -26.6913 0
-45.1151 -25.9817 0
...
&
faces_flatmap
48206 48190 46887
48221 48205 46896
46893 48218 48219
...
Yet, if I call
Hpa = patch('vertices',vert_flat,'faces',face_flat,...
'EdgeColor',edgecolor,'FaceColor',facecolor);
it comes up with an error: Warning: Values in patch Faces must be in
[1 : rows(Vertices)] - not rendering.
I suppose this relates to the fact that it is a subset of the actual
complete surface and that it therefore does not start with index 1
(but 48206 instead). Any suggestions how to proceed from here?
In the end, I'd like to visualise an overlay (saved as .w file) onto
the flattened patch instead of on the inflated surface.
Kind regards and thanks in advance,
Cris Lanting
