[PyMOL] mapping atom names between molecules

2012-08-09 Thread Krisztina Feher
Hi, I have two chemically identical molecules, but with different residue names, residue numbers and atom numbers. However the atom coordinates are also different. Is there some script that could map down the atom names, residue names and numbers to each other? Thanks for any ideas! Krisztina

[PyMOL] smooth loops

2012-08-09 Thread Yamei Yu
Hi all, In pymol. does it possible to smooth some of the loops in a structure? I use command: set cartoon_smooth_loop=1, 10g3a and c. L the software give me: Setting: cartoon_smooth_loops set for 1640 atoms in object "10g3a". But there is nothing changed in the image window. Many thanks! yam

Hi Yamei, The cartoon_smooth_loops setting is an object-based setting, so it cannot be done as you're attempting. You can do some finagling though to get close: # fetch a protein fetch 1rx1, async=0 # show it as cartoon as cartoon # select a region to hide select to_hide, i. 116-132 # cre

[PyMOL] Forcing alpha-helices

2012-08-09 Thread Alex Truong
Hi All, I'm trying to manually model a linker region using computational information (such as which residues are predicted to be in helical form, etc.). I have the sequence in PyMOL as an unmodeled linear chain (or whatever the program chose to do with bond angles when I manually generated the seq

Hi Alex, To alter secondary structure properties of atoms use the alter command: # make all atoms in the my_helix selection become alpha helices alter my_helix, ss='h' PyMOL will only draw, to the best of its ability, the helical representation. It will not adjust the atom coordinates for you.
