[gmx-users] retrieve box size from .trr or .tpr

[Saman Shahriyari]

thanks for your help. these are the parameters yielded as I picked .pdb of a frame from .trr :
REMARK    GENERATED BY TRJCONV
TITLE     Protein in water t= 10000.00000
REMARK    THIS IS A SIMULATION BOX
CRYST1   80.136   80.136  120.203  90.00  90.00  90.00 P 1
i think the box size should be as "80.136   80.136  120.203".
in an other case i used the "editconf -f mMARK2-CagA.gro -o mMARK2-CagA_emptybox.gro -c -d 1 -bt cubic" command and thye box vector is reported as "new box vectors :  "9.235  9.235  9.235 (nm)". i douted whether i should consider the box size as"9.235+1  9.235+1  9.235+1 (nm)" because of using " -c -d 1" and accounty this for the first case or not?
regards
saman

Hi Saman,

You can convert the tpr file to pdb/gro with editconf, and you can convert (a frame of) the .trr file to gro/pdb with trjconv.

Hope it helps,

Tsjerk
