MOLINFOThis command is used to provide information on the molecules that are present in your system. More details STRUCTUREa file in pdb format containing a reference structure=npt_del.pdb
WHOLEMOLECULESThis action is used to rebuild molecules that can become split by the periodic boundary conditions. More details ENTITY0the atoms that make up a molecule that you wish to align=1-4634
# Distances describing the two saltbridges K745(NZ):E762(CD) and K745(ΝΖ):D855(CG)
# that reflect the conformation of the aC helix
# (CVs described in Ludo's paper doi:10.1073/pnas.1221953110)

K745_E762: DISTANCECalculate the distance/s between pairs of atoms. More details ATOMSthe pair of atom that we are calculating the distance between=745,933
K745_D855: DISTANCECalculate the distance/s between pairs of atoms. More details ATOMSthe pair of atom that we are calculating the distance between=745,2438

# Distance between the two distance
# When both saltbridges are formed, the distance between the two distances (CV)
# is close to 0. This CV is able to characterise the displacement of the fuctionally important
# E762 located in the aC helix of the N-lobe in its transition from the so-called "aC-in" to "aC-out" conformation
