I'm asking, if I find some region can be an alpha helix, is there any easy way to let there fold into an alpha helix? I'm not meaning how to set a region looking as a helix. Thanks!
modes --> structure
right click on segment, then choose "helix"
your answer is exactly what I'm not asking...
I'm asking, if I feel some region could be folded as a helix, but it's not (in my opinion) correctly folded, is there any simple way to let it curl in the helix shape?
yes. use tweak and 'straighten' it
Or rebuild when there's a region you want to add to an existing helix, and you don't want to affect the bit of the helix that is already there.
Polyhedron.... I somehow read your question as saying exactly the opposite, that you *didn't want to know how to perform the operation....I don't know why, maybe the wording, maybe I was tired, but in any case, please accept my apology.
Both Firejuggler and gringer's answers are exactly what I would ahve suggested if I'd had my head on straight!
oh dear, xiando, that was a huge mistake indeed... good thing you apologized so gracefully :P
