<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;">Hi Steve,<div class="">(1) Labels. Not a silly question, there are just some Chimera quirks! What you have is a residue label, so use “Actions… Label… residue… off” (or command “~rlabel”) rather than "Actions… Label… off” (which is like command “~label”).</div><div class=""><br class=""></div><div class="">You can remove the A, however, by choosing “Actions… Label… residue… custom…” and then using </div><div class=""><br class=""></div><div class="">%(name)s %(number)s</div><div class=""><br class=""></div><div class="">in the resulting dialog. You can move the label with the mouse if you first assign some mouse button to do it (menu: Favorites… Preferences, Category: Mouse). To try this I changed Ctrl-3 to move-label instead of center-atom. You can also change label size in the Preferences, Category: Labels.</div><div class=""><br class=""></div><div class="">However, for figures I think the 2D Labels are much better than these “3D labels” that move along with the structure. The 3D labels are mainly for interactive use, whereas once you have decided upon the view for a specific figure, you can put 2D labels anywhere in the screen, multiple different sizes, colors and fonts (whereas all of the 3D labels have to be the same size and font as each other). You can just directly enter the text of the 2D label and drag it around with the mouse, without having to use the Preferences. See Tools… Utilities… 2D Labels or command “2dlabels”</div><div class=""><<a href="http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/2dlabels/2dlabels.html" class="">http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/2dlabels/2dlabels.html</a>></div><div class=""><br class=""></div><div class="">Takes a little learning but you can get a much nicer result. Example image attached below.</div><div class=""><br class=""></div><div class="">(2) Those lines are because adjacent residues are displayed and then Chimera tries to show the connectivity with a CA-CA bond. You can turn this behavior off. For example, command “select” to select everything, and then click the green magnifying glass icon near the bottom right corner of the Chimera window to open the Selection Inspector. In that dialog, Inspect: Molecule model and set auto-chaining to “off”. (Or just use command “setattr m autochain false” but that is probably harder to remember).</div><div class=""><br class=""></div><div class="">For a cleaner appearance, you might also want to hide H atoms, command: ~disp H</div><div class=""><br class=""></div><div class="">I hope this helps,</div><div class="">Elaine</div><div class=""><div class="">----------<br class="">Elaine C.
