As it says in the title, I would like to know the “units” of the landmark points created by BigWarp. For example, if a point has coordinates (10,10,10), does that refer to 10 pixels in x, y, and z from (0,0,0), or would that be the physical units (in my case microns)? I ask because when plotting a 3d scatter plot of the landmarks, the moving and fixed landmark point clouds are drastically different sizes. This made me think that the units where in pixel space rather than physical (microns) space. However, when I multiply the coordinates by microns/pixel for x, y, and z, the point clouds are still clearly not in the same physical space. But, when I multiply only the moving space landmarks by microns per pixel and not the fixed space, the point clouds look about right.
Am I correct in assuming that the fixed landmarks are in physical units, while the moving landmarks are in pixel space? Or am I completely off base? Any help is much appreciated.
