I want to create a lot of distance objects (in the hundreds)
between particular atomic pairs. Obviously I can make a
script like the following, inserting the exact atomic
selections that I want:
distance distobj12 = (atom1), (atom2)
distance distobj34 = (atom3), (atom4)
... etc.
But in fact one *can* still turn them on and off, with the "enable" or
"disable" command on the command line:
enable _dist1
disable _dist1
And it would be straightforward to put those commands within a loop:
# turn them all off:
for i in range(100):
cmd.disable("_dist1%s" % i)
# turn them all on:
for i in range(100):
cmd.enable("_dist1%s" % i)
Change "100" to whatever is appropriate.
I was just about to write something like this. In fact, I have tons of
files called something like x.py sprinkled around that do things like
-----------------------------------------
from pymol import cmd
num_dist = 100
def show_dist():
""" show all of my distance objects """
for i in range(num_dist):
cmd.enable('_dist%s'%i)
def hide_dist():
""" hide all of my distance objects """
for i in range(num_dist):
cmd.disable('_dist%s'%i)
cmd.extend('sd',show_dist)
cmd.extend('hd',hide_dist)
-----------------------------------------
You could also try something cute like
def show_dist():
dists = [name for name in cmd.get_names() if cmd.get_type(name) ==
'object:distance']
for name in dists: cmd.enable(name)
etc.
if you don't want to have to keep track of how many there are.
