Hi @olibclarke,
Apologies for the delay. The plot behaviour is currently a bit confusing, and we’ve made a note to make exactly what’s plotted clearer. However, as of v4.3, what’s plotted in the orientation/shift change histograms is as follows:
- If “Re-center rotations each iteration” is off, it will plot the cumulative change in the poses from the initial poses at the start of the job
- If “Re-center rotations each iteration” is on, it will plot the per-iteration change (not cumulative)
- This is true also for the “Re-center shifts each iteration” and the shift histogram.
Basically it will plot the deviation of the optimal pose/shift from the center of the pose/shift search grid, where the center of the grid is either fixed or moves around based on the value of the re-centering parameter. Likely we’ll add plots that show both cumulative and per-iteration changes as it makes sense that both of these could be informative.
