Hi Thomas,
Just a little change to make the crosshair script better. Now the
crosshair always stays put and doesn't float near the center.
python
from pymol import cmd
def crosshair_put_center():
t = cmd.get_position()
m = [1, 0, 0, t[0], 0, 1, 0, t[1], 0, 0, 1, t[2], 0, 0, 0, 1]
cmd.set_object_ttt('crosshair', m, homogenous=1)
cmd.load_callback(crosshair_put_center, '_crosshair_cb')
cmd.pseudoatom('crosshair', pos=(0,0,0))
cmd.show_as('nonbonded', 'crosshair')
python end
Cheers,
-- Jason
