Re: [AMBER] combining trajectories

Hi,

It's always useful to check your output for errors and warnings. In
your case the relevant message is at the end:

WARNING in ptraj(): No input trajectories specified (trajin), aborting...

You need to specify your combined trajectory with a 'trajin' command.

Also, I notice a lot of messages like this in your output:

WARNING in ptraj, acceptor: No heavy atom was selected (:HIP.ND1,NE2),
ignoring...

You may want to try using the 'hbond' command from cpptraj instead,
which is a little easier to set up (in my opinion at least).

Hope this helps,

-Dan
