[Chimera-users] fiting onto density map

[Elaine Meng]

Hi Urszula,
You can adjust the voxel size of your map  in the Coordinates section of the Volume Viewer dialog (show this section using Volume Viewer menu: Features… Coordinates).

However, it is unclear what exactly the correct size should be.  You may need to consult the source of the map.
I hope this helps,
Elaine
