Hi,
1. Is there an easy way to get the average structure from a MD simulation
using VMD?
My alternative is to get all the coordinates (aligned for each frame) and
make a script of my own in order to generate an average structure. Just to
make sure when one use the python command align() in a loop over all the
frames - e.g
for i in range(k):
cas = sel.AtomSel('protein')
cas.frame(i)
cas.align()
one gets the coordinates with the least difference?
I have a last question regarding the use of BigDCD - I would like to get
my coordinates out from a MD simulation where the size of the DCD-file
exceeds my physical RAM:
import Molecule as mol
m = mol.Molecule()
m.load('protein.psf')
m.load('min_prot.dcd')
is it possible to include the bigDCD into the python mode?
Thanks in advance
-- Best Regards Per Jr. Greisen
