Chimera shows the 4.6 trajectories I have on hand without problem, and there shouldn't be any incompatible changes between the 4.6 and 4.6.5 releases. Therefore I think I'm going to need (some of) your data to figure out the problem. Can you send me your .tpr file and a few frames of your .xtc/.trr file? You can write out a .xtc/.trr of just the first few frames of your trajectory with Gromacs' trjconv tool with the -dropover flag.

The old trajectories from gromacs 4.5.5 load with out any problems. Has anyone else experienced this?
