Dear Amber users:
I am carring on several similar MD calculations with ligand binding to
different interesing sites. And I meet a problem when using ptraj to
process one of the trajectory whileas others are OK when doing the same
thing.
What I want to do is just to remove waters and counterions from the
trojectories. I found when I tried to remove Na+ from the trajectory, each
frame in the outputted trajctory was in disorder when displayed in VMD. I
also checked the initial trajectory file, it looks well.
The ptraj script is as below:
trajin test.traj.gz
strip :WAT,Na+
trajout test.out.traj.gz nobox
Attached please find test.tgz, a file containg topology, trajctory and
ptraj script file.
I hope anyone of you could tell me what's the problem with my file/script.
Thanks in advance!
Best Regards!
liu
