° | 'AltLoc' switches to a selection of alternate conformations |
Sometimes a bunch of atoms (mostly side-chains) can be seen at two or more distinct locations in the X-ray density map. These atoms are then present multiple times in the PDB file,
but with different 'alternate location (AltLoc) indicators'. The 'AltLoc' selection type allows to choose one of these multiple conformations.
Examples:
DelAtom AltLoc B | Delete all atoms with an alternate location indicator 'B' |
DelAtom AltLoc B-Z | Delete all atoms with AltLoc indicators B to Z |
