Slicer version: 4.8.1
Expected behavior: Any numerical input allowed
Actual behavior: input limited to numbers greater than 0.01

I have transform files that are output by ANTs (https://github.com/ANTsX/ANTs) and associated image data. However the voxel sizes are 0.024 or smaller and I’d like to be able to visualize the deformation field but I’m limited in how small I can make the spacing, how large I can make the scale factor, etc.

Is there some way to override these safeguards?

You can set the values using the Python console, for example:

getNode('LinearTransform_3').GetDisplayNode().SetGlyphSpacingMm(0.01)

I’ll have a look how the range could be made more customizable using the GUI.
