If you want to save atoms, bonds and surfaces and load them into Chimera later, then save a session, menu File / Save Session As….

When I save it as OBJ file, how can I watch it in chimera again as a molecule with "atoms" and "bonds" (like CONECT line in pdb file)?
I see that OBJ file look like a xml file, and contains coordinates and edges, but does it reflect the mesh?

Thanks,
Amichai

Hi Amichai,

  Chimera computes density map isosurfaces using the marching cubes algorithm.  It can be saved in various file formats for example OBJ, others are described with the export command

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,
