Editing Alter (section)

====Renumber the amino acids in a protein, so that it starts from 0 instead of its offset as defined in the structure file====
<source lang="python">
# The first residue in the structure file for 1cll is 4.  To change this to 0, maybe to match scripts
# outputted from other programs, just remove the offset of 4 from each atom
alter 1cll, resi=str(int(resi)-4)
# refresh (turn on seq_view to see what this command does).
