Re: [chimera-dev] [Chimera-users] Is there any tool to write some calculated attribute into a header format?

Thank you very much, Eric. Unhappily I am not familiar with Python scripting, so I will have to wait that someone with that skill adds this useful tool into Chimera code! But for now I will take Elaine's hints!

Save density map as a mesh
by עמיחי הולצר 30 Jul '18

Hi Chimera support, I have 2 questions: 1. How does Chimera calculate the mesh from the density map? 2. How can I save the mesh as a file? Thanks a lot, Amichai Holzer Huji

Re: [chimera-dev] Dust Clean in cryo-EM maps

Hi, I like the density map after hide density map, is there any way to save the density map after dust hide? Every time I save the density map, it saved the original map instead of density map after hidden dust.
