[PyMOL] Question on geometry option in replace command

[Lei Q. <lei...@ou...>]

Dear users,
Could I ask a question on geometry option in replace command?
I tried to use Build/Fragment/XXX to replace an atom to a new one, and pymol GUI shows the corresponding replace command.
However, I found the geometry option always equals to 4.
For example,
PyMOL>replace O, 4, 2
PyMOL>replace N, 4, 3
PyMOL>replace C, 4, 4
I tried to replace the atom in different types of bonds: single/double/triple bonds, but the geometry value is always 4.
Could you please help me figure it out? Thank you very much!
Best,
Lei
