I have an ion in a membrane transporter which I am simulating in MD, now, I need in order to pull the ion outside the transporter to use a vector to identify a water molecule which is exactly in the direction of the exit tunnel. For that purpose I need to draw such a vector or to at least identify a water molecule in the right direction. Can Chimera help me with that?

I mean is there a way to identify which water is on the exact pathway of the ion exit?

How can I do it?

Thanks a lot in advance,

Fabian
