As I recently learned from messing with ANTS, ITK's coordinate system is
+x=left, +y=posterior, +z=superior, while the nifti coordinate system
(which workbench uses) is +x=right, +y=anterior, +z=superior. This is the
reason for the negations on x and y.

Hi all and thanks for your answers,
Just as a quick follow up I figured out how to align the vtk and images after
conversion. The thing is I am using medinria that seems to read the nifti
header differently (through the ITK reader) than workbench is. Basically, I
have seen thanks to the wb_comm
Workbench does not apply any additional transforms: the coordinates the
file specifies are the ones it uses, directly (it actually ignores the
affines in the gifti file, but writes an identity affine since gifti
unfortunately requires at least one affine written there). You can
identify a vertex b
Workbench does not transform the GIFTI Surface Files. Workbench draws volumes
in coordinate space (not voxel IJK space) using the NIFTI ‘sform’ or ‘qform’.
If the software you are using ignores the NIFTI ‘sform’ or ‘qform’ that may be
why the data does not align.
‘wb_command -file-informati
What tools are you using that require VTK?
Peace,
Matt.
