Extract voxel coordinates of 3D render
Hello team,

I used the MRIcroMTL to get a 3D render of a patient's brain (see attached), and I'd like to extract the voxel coordinates of various locations on this render. Is there a way to do that?

Thanks,
Ayan

RE: Extract voxel coordinates of 3D render
Hello,

Sorry I missed this. You will want to upgrade to the latest MRIcroGL (v1.2.20211006)
  https://www.nitrc.org/projects/mricrogl/
The Display menu has a new item "Multi Planar A+C+S+R" which visualizes three 2D slices and a 3D rendering. Crosshairs are shown on each slice and clicking at any location moves the crosshairs to that location. The coordinates are shown in the title bar.

This is described here:
