[gmx-users] Fwd: gmx trjcat

[Paul bauer]

Hello,

this looks like a case of misleading documentation. Can you file an 
issue for this please on redmine.gromacs.org?
So that we don't forgot to fix this for the next patch release?
A possible work around for you can be that you first convert your files 
to e.g. XTC format, use trjcat to combine them and convert them back to GRO.

Cheers

Paul
