[gmx-users] permeation events- ion channels in bilayer

[Alex Mathew]

Dear GMX users,

We are looking for water permeation events across the ion-channel, which is
embedded in lipid bilayer. After one micro second MD simulation in
Gromacs2016.1 i used the below script for calculating the  permeation
events,

nanotubes/files/permeation.tcl

Unfortunately all the time it gives zero value (I have tried for different
upperEnd  and lowerEnd ), but i can visualize the water movements in VMD
screen.

Kindly provide your valuable suggestions, since i don't have much expertise
in coding/programming.

Alex
