[COOT] Flip (histidine) sidechain 180 degrees

[wtempel]

Hello,
is flipping a His side chain using the button on the right-hand toolbar
working for you as expected? In our hands, starting with version 0.8.9 (?),
the "side chain flip", applies a 180 degree chi-2 rotation keeping the
imidazole moiety fixed and disrupting the protein main chain. Gln and Asn
flips work as expected.
Thanks.
