<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; ">Hi Darrell,<div><span class="Apple-tab-span" style="white-space:pre"> </span>Good idea. I've implemented a version of this by adding an entry to the popup menu you get when you control-double-click an atom. The menu will have a "Show distances to nearby atoms" entry that shows all distances to non-bonded atoms within 4 angstroms (and hides distances you showed previously). If you bring up the menu a second time on the same atom the entry will be "Hide...(etc)". The feature will be in tonight's daily build. The actual menu text isn't set in stone so it might change slightly in the next few days but it'll still be obvious which entry it is.</div><div><br></div><div>--Eric</div><div><br><div><span class="Apple-style-span" style="border-collapse: separate; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 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; -webkit-text-decorations-in-effect: none; text-indent: 0px; -webkit-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><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></span></div><div><br class="webkit-block-placeholder"></div><div><div>On Apr 30, 2012, at 12:52 PM, Hurt, Darrell (NIH/NIAID) [E] wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div>Hi everyone,<br><br>This brings up a feature that I've been missing in all visualizers that I've tried. It exists (or at least used to) in "O". When you click on and select an atom using a special mouse modifier, the software would "reach out" and display all distances to other atoms within a pre-specified radius. Sometimes it is hard to judge how far away other atoms are from a selected atom. The times I use measuring tools the most is when I'm trying to identify "nearby" atoms. While it is true that we have the "Zone" selection and similar tools, I think that it would be really nice to have a tool that "looks for" close contacts and displays their distances using pseudobonds given a simple click. The next click would either turn off the pseudobonds or display those associated with the next selected atom.<br><br>Can you see what I'm trying to describe?
