[chimerax-users] Error in ChimeraX application installation linux ubuntu

[Elaine Meng]

Hi Vanessa,
Please send ChimeraX questions to chimerax-users at cgl.ucsf.edu (CC'd here, so no need to do anything this time).

Since I don't know the answer, I kept waiting for somebody else to answer your question... and didn't notice until now that you had sent it to only me.

Thanks,
Elaine
