Now, instead of a picture, how do I do the same for a chimera type of volume display? Do I have to also go through creating a frame, a canvas, and then indicate that the volume must reside in the just created canvas. It would be great if you know of any example out there. I have been relying on examples so far. <br class=""></div><div id="yui_3_16_0_1_1425677795525_8814" class=""><br class=""></div><div id="yui_3_16_0_1_1425677795525_14616" dir="ltr" class="">Thanks again!</div><div id="yui_3_16_0_1_1425677795525_14617" dir="ltr" class=""><br class=""><span class=""></span></div><div id="yui_3_16_0_1_1425677795525_11080" dir="ltr" class=""><span class="">Stu</span></div> <div class="qtdSeparateBR"><br class=""><br class=""></div><div style="display: block;" class="yahoo_quoted"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" class=""> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" class=""> <div dir="ltr" class=""> <font face="Arial" size="2" class=""> On Friday, March 6, 2015 4:26 PM, Tom Goddard wrote:<br class=""> </font> </div> <br class=""><br class=""> <div class="y_msg_container"><div id="yiv3634815349" class=""><div class="">Hi Stu,<div class="yiv3634815349"><br class="yiv3634815349" clear="none"></div><div class="yiv3634815349"> To find out about Python functions that control volume display in Chimera that you could use from your Tkinter gui take a look at the Chimera Python scripts web page:</div><div class="yiv3634815349"><br class="yiv3634815349" clear="none"></div><div class="yiv3634815349"><span class="yiv3634815349Apple-tab-span" style="white-space:pre;"> </span><a rel="nofollow" shape="rect" class="yiv3634815349" target="_blank" href="http://plato.cgl.ucsf.edu/trac/chimera/wiki/Scripts">http://plato.cgl.ucsf.edu/trac/chimera/wiki/Scripts</a></div><div class="yiv3634815349"><br class="yiv3634815349" clear="none"></div><div class="yiv3634815349">for example the readvol.py example shows how to access volume data values.
