What is paraview? I would contact the developers.

Hi all,
I have a similar problem using Paraview:
When I visualize the surface lh.pial and the anatomical image
brainmask.mgz using FreeView they nicely overlap; however, after I
convert lh.pial to lh.pial.vtk and brainmask*.mgz* to brainmask*.mha*
and visualize them using Paraview, they are in different spaces.
Do I need to apply a transformation matrix to lh.pial using the
command line mri_surf2surf so the VTK surface will overlap with the
image when using Paraview?
I find this quite confusing.
Thanks!
Kindly,
Islem

tksurfer always uses the ?h.orig coordinates. Also keep in mind
that the vertex index is 0-based whereas matlab is 1-based. When
you click on a point, you should see something like the following
print out
selected vertex 123491 out of 163842
current -39.11 15.65 11.26
orig -55.67 -10.37 19.95
pial 0.00 0.00 0.00
white -55.76 -10.29 19.93

Dear Experts,
I tried to extract vertex coordinates information from
‘fsaverage/surf/lh.pial’ file using matlab function ‘read_surf’,
but I found that the coordinates returned by the function are
different from what I saw in tksurfer, here are the screenshots:
The vertex index starts from 0 in tksurfer, so I select the
second elements in matlab. Why is the result different from what
has been shown in tksurfer(also different in freeview)? Which one
should I report?
Is there any way to transform the surface coordinates to the
MNI152 space?
Thank you very much!
Dong
