GROMACS version: 2020.3
GROMACS modification: No
I have been using gmx trjconv -f abc.xtc -s abc.tpr -pbc mol -ur compact -center to remove periodicity from trajectory of a monomeric protein. It works as expected. However, recently I had to use gro as a reference file (for -s) and I see it does not give me the result which tpr file gives. The tpr file is generated using the same gro file, hence the reference structure is exactly same. The expected result is an intact molecule centered in the box. With gro file, I still get a broken molecule.
I am not sure if the behavior of trjconv has changed with respect to gro and tpr files. If not, is it a bug?
