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

Hi I want to import a Gromacs trajectory (a .trr file) in order to create an animation. I'm using the "MD Movie" tool, and I specify the input .tpr and .trr files. However, I get the following error when I try and make the movie: Don't know correct parameters for 'bham_lr' function Does anyone know what this is from? I'm using Gromacs 5.0.4. The complete Reply Log is as follows: using memory mapping VERSION 5.0.4 using floats version 100, generation 26 2613 atoms box o water Don't know correct parameters for 'bham_lr' function Thanks!
