Not while mdrun is running; that will kill the run.  The most important part of 
the run is the trajectory, so if you delete the .trr you'd better have the .xtc 
as well, otherwise there was no point in doing the simulation.  Better planning 
(in terms of frequency for saving frames) and paying attention to what grompp 
tells you about how much data will be generated pay off here.
