Hi ChimeraX team,
I'm running into unexpected behavior when using the build tool.
Here's what I'm doing:
- open map --> model #1
- open PDB --> model #2
- fit #2 in #1 (the PDB moves by ~20 Å at this step)
- cofr centerOfView showPivot true
- move the view around so that the pivot axes intersect where I want to place a new atom
- build start atom #2
expected result: a new H atom is created exactly at the center of view (where the pivot axes intersect)
actual result: the new H atom is created some distance away; I think the vector from where the new H atom is built to the cofr is the same vector as the PDB model was displaced by the fitting into the map (my second step, above), but I haven't checked that carefully.
Is this what is expected? It confused me :)
Is there a command I can use to move the atom to the correct location after it's been created?
Interestingly, if I add a H atom into a new model, then it appears where I expect it, at the cofr:
- build start atom "custom built"
This is with 1.2.5 (2021-05-24)
Cheers,
Alexis
