<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; line-break: after-white-space;">Hi Kate,<div class="">Yes, the MOLEonline scripts are written just for Chimera. ChimeraX is a different program and won't work with Chimera sessions or python scripts written for Chimera. </div><div class=""><br class=""></div><div class="">Chimera does have an option to export a file for input to ChimeraX, but it only includes the atomic/ribbon displays, not yet surfaces (but see below, to my surprise it worked!). If the reason for using ChimeraX is display only (not calculations requiring atomic data), other Chimera export formats may also work, like Collada. ChimeraX can read Collada files.</div><div class=""><br class=""></div><div class="">See Chimera menu: File... Export Scene, options include ChimeraX and collada:</div><div class=""><<a href="https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/export.html" class="">https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/export.html</a>></div><div class="">... or Chimera's "export" command:</div><div class=""><<a href="https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/export.html" class="">https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/export.html</a>></div><div class=""><br class=""></div><div class="">Just now I tested exporting a Chimera scene showing MOLEonline results (Chimera 1.16 daily build from August was what I had handy) and even though I got a warning message that the export to ChimeraX file does not work for surfaces, to my surprise, when I open it in ChimeraX, voila! It does include the tunnel displays! So maybe it WILL work for your situation. You may have to change the background color yourself. I was also able to export collada (.dae) file from Chimera that gave the same display when opened in ChimeraX. The ChimeraX choice is better than collada, since it will also include all the other tunnels that aren't displayed when you export, see screenshot below:</div><div class=""><br class=""></div><div class="">Best,</div><div class="">Elaine<br class=""><div class=""><div class="">-----<br class="">Elaine C.
