First public release of Geopickr — a ChimeraX bundle for geometric particle
picking in cryo-electron tomography.
One tabbed tool with Place Points, Geometry Picker, and Place Object:
mark sphere centres / tube & filament axes, geometrically sample evenly-spaced
particle positions and orientations on spheres, tubes, filaments, or arbitrary
surface meshes, and display the resulting TOM/AV3 motive list. Export .em or
STOPGAP .star.
Install
Download the wheel below and, in ChimeraX:
toolshed install /path/to/chimerax_geopickr-1.0.0-py3-none-any.whl
Then open Tools → Volume Data → Geopickr. (A Toolshed listing is planned so
this can be installed directly from within ChimeraX.)
