<html><head><meta http-equiv="Content-Type" content="text/html charset=utf-8"></head><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Hi Oliver,<div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>We discussed this at the meeting today and the upshot is that we are very interested in doing this, but it will take us awhile to get to it. We intend to make a beta release of ChimeraX by the end of the year and there’s a lot of work to get done between then and now. Part of that work is to implement the “Nucleotides” representation that you see in regular Chimera but that isn’t yet available in ChimeraX. The “alternative atom depiction” that Nucleotides provides requires much of the same underlying support that showing the alternative carbohydrate depictions will require. Implementing Nucleotides first will allow us to iron out the issues involved in supplying that support and debug it. That will make implementing the 3D-SNFG representation much faster and improve its reliability. So we hope to be able to provide the carbohydrate depictions not long after the beta release date.</div><div class=""><span class="Apple-tab-span" style="white-space:pre"> </span>I’d like to provide something faster, but as a practical matter I think this is the best we can do. I’m sure we will have questions about the details once we get onto the implementation, and hope you won’t mind if need to bug you a bit. :-)</div><div class=""><br class=""></div><div class="">—Eric</div><div class=""><br class=""><div class="">
