[Chimera-users] Opening Gromacs .trr: error with "bham_lr"

[Elaine Meng]

Hi Alan,
Probably you need to get a newer Chimera.  You didn’t say what version of Chimera you were using, but Gromacs support was added after the 1.10 release, so you would need to get a 1.11 daily build.

Changes since 1.10:

Download daily build:

I hope this helps,
Elaine
