"replace new_atom, ..." Replace pk1 with New Atom

This section provides a tutorial on how to replace the first picked atom pk1 with a new atom using the 'replace ...' command in PyMol.

If you want to change the first picked atom, pk1, you can use the "replace new_atom ..." command.

replace new_atom, new_geometry, new_valence

For example, the following command replaces the first picked atom with "C" atom and sets geometry to 1 and valence to 1.

replace C, 1, 1

Note that you can use any integer value for geometry and valence properties of the new atom. And you can change them with the "set_geometry" command later.

For example, the following command script will pick the atom at the index of 7 and replace it with Nitrogen atom

delete all
reset
load Molecule-HY-001.sdf
hide all
show sticks
turn z, -90
edit id 7
replace N, 1, 1
