[gmx-users] Trjconv problem invalid argument

[Poncho Arvayo Zatarain]

Hello Gromacs users: I want to obtain the density of a system using the command: gmx_gpu density -ng trjconv -f file.xtc -s file.tpr -o out.xtc -skip 100, but the following error appears: Invalid command argument: trjconv. What is wrong with trjconv? I am using gromacs 5.0.3

Thanks
