Re: [gmx-users] on -dt of trjcat and trjconv

[Erik Marklund]

Dear Brett,

MOD refers to the modulus operator. For example, trjconv -f infile.xvg -s 
infile.tpr -dt 1000 -o outfile.xvg will downsample a trajectory and save only 
the frames at multiples of 1000 ps (0 ps, 1000 ps, 2000 ps, …), assuming that 
infile.xvg starts at 0 ps.

Kind regards,
Erik

[gmx-users] on -dt of trjcat and trjconv

[Brett]

Dear All,

For both trjcat and trjconv, there was an option "-dt", which the on-line 
GROMACS material explained as following, "Only write frame when t MOD dt = 
first time (ps) ".

Will you please explain to me what is the meaning of "Only write frame when t 
MOD dt = first time (ps)", by a detailed example with command?

Brett
