[gmx-users] how to assign options of the same type?

[Zhang, Cheng]

Dear GROMACS,

Can I ask how to assign options of the same type?


For example, on the website of

http://manual.gromacs.org/current/programs/gmx-mdrun.html


It is said in the "Synopsis":


[-o [<.trr/.cpt/...>]


I want to name the output files as md.trr and md.cpt. However, the followings do not work:


-o md.trr md.cpt

-o md.trr/md.cpt

-o md.trr -o md.cpt


So do you know what is the syntax?


Thank you very much.


Yours sincerely

Cheng
