[Chimera-users] Set a reference coordinate for a viral structure?

[Tom Goddard]

Hi Yuzheng,

  First I advise you to use ChimeraX which is the new version of Chimera.  We have not developed Chimera for the last 6 years so it is best to use the new program if you are not yet tied to the old one.

  The description of the virus coordinate system transform is not clear.  I see that supplementary figure S4 of the paper you cite has a similar unclear explanation (shown below).  It would probably take reading the paper to understand what they did well enough to understand the coordinate transformation.  If you have read it and can explain it clearly then I could advise on how to do it in ChimeraX.
