[gmx-users] concatenate of .edr files

[dina dusti]

Dear GROMACS Users,

I have simulations with 1200000 ps and the file names are md.*, then I expended the time of simulation to 2400000 ps, with file names next as are follow:

tpbconv -s md.tpr -extend 1200000 -o next.tpr
mdrun -v -deffnm next -s next.tpr -cpi md.cpt

I use from trjcat to concatenate md.trr and next.trr but I don't know that how should I concatenate the md.edr to next.edr!
May I ask you to help me, Please?
Best Regards
Dina
