<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi Julius,<div><span class="Apple-tab-span" style="white-space:pre"> </span>There is no command equivalent for that part of Render By Attribute unfortunately. I've put making a command equivalent on a to-do list. So you will have to resort to the Python part of the per-frame scripting dialog. I've attached a Python file that goes through currently open molecules and writes out the areaSAS attribute of residues into files named /var/tmp/sasNNN where NNN is 001 for frame 1, 002 for frame 2, etc. You will of course have to have added a surface. You can use the "Insert text file..." button of the per-frame dialog to directly enter the script from the file.</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>If you know Python, the script is pretty straightforward. The only tricky part is right at the beginning where it calls checkForChanges(). This allows the surface-computation code to immediately notice that the structure coordinates have changed and recompute the surface. Otherwise, the surface-computation code wouldn't get that notification until after the per-frame script had run, so the surface areas we print out would always be off by one frame.</div><div><br></div><div>--Eric</div><br><br><div><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><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 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 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><br></div></div></div><div></div></body></html>
