Hi all, For any of you using Chimera's MD Movie for trajectory playback, I just added the ability to plot atomic distances, angles, and dihedrals for your trajectory. You can click (or drag) on the plot to go to the corresponding frame. You create a plot by using the "Plot" submenu in MD Movie's Analysis menu. Most of the functionality is available in the current daily build, but tomorrow's build will have a couple of additional features: dumping plot values to a file, and showing the numeric value of the plot for the current frame in the list of plots (the value is blanked during playback since updating it slows down playback too much). Feedback welcome. --Eric Eric Pettersen UCSF Computer Graphics Lab http://www.cgl.ucsf.edu
