Path D - Module 31: Proximity & Neighborhoods

Which lipids are directly touching the channel? In this module, you will learn to identify Annular Lipids using proximity thresholds.

import molsysmt as msm
from molsysmt import systems
system = [systems['POPC membrane']['popc_membrane.h5msm'], systems['POPC membrane']['popc_membrane.dcd']]
annular = msm.get_neighbors(system, selection='molecule_type=="protein"', selection_2='molecule_type=="lipid"', threshold='0.4 nm')
