I am trying to show some cell surface receptors and to indicate their position
relative to the membrane.
I thought to indicate the plane of the membrane by a flat disk, a ago cylinder.
x1,y1,z1 = 0, -1, 0 # start point
r1,g1,b1 = 1, 1, 0 # color (yellow)
x2,y2,z2 = 0, -2, 0 # end point
r2,g2,b2 = 1, 1, 0 # color (yellow)
radius = 100
cmd.load_cgo( [ 9.0, x1, y1, z1, x2, y2, z2, radius, r1, g1, b1, r2, g2, b2 ],
"membrane" )
When I try to move this cylinder into the correct position with
cmd.transform_selection,
using the transformation parameters extracted from get_view (reordering them as
needed)
I get the error message "Selector-Error: Invalid selection name “membrane” “
The same transform command works fine if I apply it to a pseudo atom originally
generated with coordinates 0,0,0.
Any suggestion how else I could indicate the membrane, or how I could place my
ego object parallel
to the screen yz plane? I have to be able to do this in a reproducible fashion,
as I have to do this
for a large number of constructs that bend my receptors relative to the
membrane in various ways.
Thanks for your help
