The RMSD plot you referenced provides a frame-vs.-frame 2D plot of RMSD variance for a selected set of atoms. So if you select the backbone atoms (e.g. "sel backbone.full" or Select->Structure->backbone->full) and ensure that "Restrict map to current selection, if any" in the RMSD dialog is set to true then the resulting plot will be just for the backbone atoms.</div><div><br></div><div>--Eric</div><div><br></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font-size: 16px; "><font face="Helvetica" size="5" style="font: normal normal normal 16px/normal Helvetica; "> Eric Pettersen</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font-size: 16px; "><font face="Helvetica" size="5" style="font: normal normal normal 16px/normal Helvetica; "> UCSF Computer Graphics Lab</font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font-size: 16px; "><font face="Helvetica" size="5" style="font: normal normal normal 16px/normal Helvetica; "> <a href="http://www.cgl.ucsf.edu">http://www.cgl.ucsf.edu</a></font></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; font-size: 16px; "><font face="Helvetica" size="5" style="font: normal normal normal 16px/normal Helvetica; "><br></font></div><div><div><div>On Jan 5, 2011, at 9:34 AM, George Tzotzos wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>I'd be grateful if you informed if there's a way one can plot protein backbone rmsd fluctuations of trajectories.
