[PyMOL] Problem

2006-08-24 Thread mahesh kulharia
Hi I need help. Can some one tell me a way to find out whether 2 molecules are connected by covalent linkage or not. Say for example in pdb files we have ligand and protein molecules and I wish to know a way to find out if the ligand is connected to the protein via a covalent bond or not, The

Hi Mahesh, There is no way to see whether two atoms are connected. Pymol guesses the connectivity based on the distances between the particles. But to be certain whether atoms are bonded, you have to look in the PDB file, which should mention covalent attachment of a ligand. At the end of the

You can also check if there is connecting electron density, see for example the electron density server at http://eds.bmc.uu.se/eds/ . This of course only works if the authors have deposited the experimental data. I hope this helps. Best regards, Anne -Original Message- From:

[PyMOL] surfaces, VDW and probe radii

2006-08-24 Thread Richard Gillilan
I'm trying to create a smooth surface representation of a set of 6.5A diameter spheres read in as CA atoms. Is there a way to override PyMol's assignment of atomic radii? Also, if I were using a conventional molecular surface algorithm I would turn up the probe radius so that the surface

HI all, This is a follow on from the e-mail below. Frequently I'm also getting this error when pymol crashes: *** glibc detected *** /home/fauxn/software/pymol/pymol.exe: double free or corruption (!prev): 0x0aaef170 *** === Backtrace: = /lib/libc.so.6[0xc69d88]
