Run STalign registration

Picks one of the bundled Visium-capture-to-Visium-capture pairs (from Kairns' cached experiment data), prescales the source capture onto the target's coordinate frame, then runs the real vendored LDDMM registration — same code path as bin/align_points.py on the CLI, launched as a background job so status can be polled across gunicorn's worker processes.

Registration parameters

Defaults match bin/align_points.py's own — 150 LDDMM iterations, the first 75 affine-only before the non-rigid warp phase starts.

Fixture pair

dx (px size)

Blur (px)

Iterations

Diffeo start

Init rotation (deg)

Rendering preview…

Instant affine-only preview (no LDDMM run yet) — updates as you change the fixture or initial rotation, so you can see roughly how the two point clouds line up before committing to a full registration.

Job

Every stage below is part of bin/align_points.py's pipeline — the static text explains what the stage does and how to read its output in general; the monospace lines under it (once reached) are this run's actual numbers.
