I am not sure but I believe it is the downsampling factor, i.e.,<br>
display a vector every ten vectors in the vector field.<br>

It is the down-sampling factor and it acts exactly as you said.<div><div class="h5"><br>

Dear Simon,<br>
<br>
There are 3 options for the deformation overlay field: subsampling, scale<br>
and width. I would like to know what units is the subsampling parameter in?<br>
I.e. If I set to 10 does it mean that it displays vectors for every 10mm or<br>
10 voxels?<br>
<br>
Best wishes,<br>

Hi Bilal,<br>
All the ITK formats should be accepted so if .nii.gz is readable ITK,<br>
it is readable by VV. It's not because the format is not listed from<br>
the gui that it cannot be read. Just give it a try from the command<br>
line, e.g., vv image.mha --vf vf.nii.gz<br>
The format is one file with the displacement vector at each point,<br>
i.e., itk::Image< itk::Vector<float, 3>, 3>. The vector is in mm and<br>
the location of the vector is given with the origin and spacing of the<br>
image, as usual in ITK.<br>

Dear VV community,<br>
<br>
I would like to visualize the deformation fields from image registration.<br>
I<br>
have been experimenting with ANTS registration which outputs warped and<br>
inverse deformation fields in .nii.gz format but I noticed that .nii.gz<br>
format was not among the list of supported formats - only the .nii format.<br>
<br>
In addition, I would like to know if VV requires a specific format to view<br>
the deformation fields? I.e. does it need the X,Y,Z images in one file or<br>
as<br>
3 separate images? In addition does it have any requirements on the<br>
intensity values of the X, Y, Z images in terms of coordinate systems?<br>
<br>
Best wishes,<br>
