Re: [PyMOL] Distorted secondary structure using 'alter' command

2013-06-14 Thread Thomas Holder
Hi Ritu, do I understand correctly that resi 3-9 are *not* in helix conformation, and you want to perform a modelling task? Altering the ss property is not sufficient, that's just an annotation and not a modelling constraint. PyMOL is primarily a visualization tool and less a modelling tool,

[PyMOL] Distorted secondary structure using 'alter' command

2013-06-13 Thread Rituparna Sengupta
Hi All, I'm trying to change a stretch of a polypeptide chain (residues 3-9) into a helix. I use the alter command: alter 3-9/, ss='H' But when I try to see the updated structure in cartoon, the structure doesn't appear like a helix. It looks like a distorted helix. How do I correct it?
