I think Mark made a typo in writing the word "maybe" here.

The point he was making is that you're trying to specify nstxtcout and 
nstxout-compressed, which is a mixture of syntax from different GROMACS 
versions.  You can't/shouldn't do that.

All of the .trr options (nstxout, nstvout, nstfout) default to zero, so a .trr 
file is only written if you ask for it by setting any one of those to a non-zero 
value.
