An MD user is typically not going to want to save what is basically a second copy of their trajectory data into a session, which is what would happen unless I do something pretty tricky during the session save. Also, Chimera's session files aren't as efficient space-wise as the original files (in the two cases I tried the session file was 64-78% larger than the trajectory files).</div><div><br></div><div>2) The MD tool is old code that I didn't originally write and isn't well designed for session saving (or command-line use for that matter). It is split into two modules that would both have to be saved and coordinated with each other and a lot of new code would need to be written to "revive" the graphical interface from a session file.</div><div><br></div><div>3) Other aspects of saving the GUI would be tricky, such as what to do about trajectories that haven't been fully loaded from their input files, but also such things as saving RMSD maps and occupancy volumes. Since the latter didn't come from volume input files they don't get automatically saved into sessions (currently the user has to save each one of them into volume files first).</div><div><br></div><div><span class="Apple-tab-span" style="white-space:pre"> </span>I an not unwilling to do the work necessary here, but I think we as a team have to decide that it is worth pushing down some other priority item to do so.</div><div><br></div><div>--Eric</div><br><div apple-content-edited="true"> <span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 16px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><div style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="5" style="font: 16.0px Helvetica"><span class="Apple-converted-space"> <span class="Apple-converted-space"> </span></span>Eric Pettersen</font></p><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="5" style="font: 16.0px Helvetica"><span class="Apple-converted-space"> <span class="Apple-converted-space"> </span></span>UCSF Computer Graphics Lab</font></p><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="5" style="font: 16.0px Helvetica"><span class="Apple-converted-space"> </span><a href="http://www.cgl.ucsf.edu">http://www.cgl.ucsf.edu</a></font></p><br class="Apple-interchange-newline"></div></span> </div>P.S.
