Re: [PyMOL] Dynamic Bonds based on connection table ?

2012-07-15 Thread Thomas Holder
Hi Thomas,

if you load the molecules as discrete objects, then the states will be 
independant and each state will have its own connectivity.

load testm.pqr, mov, discrete=1

PyMOL by default calculates connectivity based on distances. If you want 
to make sure that only your own CONECT records are used, then set 
connect_mode to 1. http://pymolwiki.org/index.php/Connect_mode

Cheers,
   Thomas

 Dear PyMOL users,
 
 I´m looking for an option to generate animations with changing bonds.
 
 So far:
 cmd.load(testm.pqr)
 cmd.load(testm1.pqr)
 = 2 objects with correct bonding from conect entries
 
 load testm.pqr, mov
 load testm1.pqr, mov
 = trajectory, but only connection table from 1st frame seems to be used
 
 small test structures (only 1 bond removed) are attached, overall 
 simulations consists of larger structures with substitution reactions 
 and a large number of time steps - therefore a loop for loading the 
 files should be possible. The conect entries per time frame are 
 calculated in the simulation, the pqr files are generated using this 
 information, either as single file/time step or as one file holding all 
 time steps. Connection table reads are not necessary every single time 
 step, but would be nice every n iterations based on typical structures 
 changes in the simulations.
 
 I'm rather new to PyMOL, so hopefully you can guide me to a solution.
 
 Kind regards,
 Thomas
