No problem! For the record, ISOLDE adds another ~200 MB - but the installation is fairly trivial via the ChimeraX ToolShed (Tools/More Tools in the menu).</div>

<div>Thanks Tristan! Unfortunately, the students tell me that the 1 GB size of ChimeraX is about what their laptops can handle, so I'm reluctant to require them to install another program to do a small part of a larger exercise. Hopefully ChimeraX will have
a Ramachandran plot at some point in the future, but I'll have other things for the students to do this year.</div>

Yep - ISOLDE certainly does have a Ramachandran plot (a rather pretty one, I like to think!).

<div>Hi Ralph,<br>
A missing tool (something in Chimera but not ChimeraX) should not be interpreted as intentionally chosen to be dropped... instead we may not have had time yet to add it. It's certainly fine to ask on this mailing list, and good for us to hear which features
users are most eager to have in ChimeraX.<br>
<br>
Since ChimeraX is built using entirely different frameworks than Chimera, tools need to be reimplemented mostly from scratch rather than simply copied and slotted in. We have somewhat limited manpower. Consider that Chimera tools were added over 15-20 years!<br>
<br>
As for Ramachandran maps specifically, there may be something like that in the ISOLDE plugin. ISOLDE is generally for rather advanced users building atomic structures into cryoEM density, but I can investigate whether it could simply be used to show a Ramachandran
map for protein structures and how difficult that might be for somebody at the student level.<br>
<br>
I hope this helps,<br>
Elaine<br>

find it in the help section. If it's not there, is there a reason it was dropped? The students find it instructive.<br>
