Hi, I have a couple of quick notes about your specific application: This works well when bilayers are flat. So, it works well for small bilayers and it works well at the beginning of a simulation. For medium to large bilayers, undulations throughout the simulation will cause this algorithm to bre

[PyMOL] select by absolute coordinate

2009-03-02 Thread Martin Höfling
I quickly checked the selection algebra and property selector wiki pages and couldn't find anything related to this. Is it possible e.g. to select all atoms with (absolute) z - coordinates greater than 5A? Best Martin
