Another way is to use the "hide" command to hide that model, e.g.</div><div class=""><<a href="https://rbvi.ucsf.edu/chimerax/docs/user/commands/show.html" class="">https://rbvi.ucsf.edu/chimerax/docs/user/commands/show.html</a>></div><div class=""><br class=""></div><div class="">hide #1.1 models</div><div class=""><br class=""></div><div class="">or</div><div class=""><br class=""></div><div class="">hide #1.1</div><div class=""><br class=""></div><div class="">(if you use the second command above, the display checkbox is still checked, since the checkbox hides at the model level whereas that command hides all the individual pseudobonds while technically leaving their model displayed)</div><div class=""><br class=""></div><div class="">Or, if there are more than one and you just want to hide a specific one, then you can select the one you want to hide with Ctrl-click and then use command</div><div class=""><br class=""></div><div class="">hide sel</div><div class=""><br class=""></div><div class="">There was a bug that made pseudobonds between ribbons hard to select, but if you get a recent daily build that problem has been fixed.</div><div class="">I hope this helps,</div><div class="">Elaine<br class=""><div class="">-----<br class="">Elaine C.
