Description

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)

Fix will be in tomorrow's build.
