[chimerax-users] A question about the level option in volume viewer

Hi ChimeraX-developers, I got a question about the level option in volume viewer. I think the level represent the isovalue for the density map. So when I set the level as 0.03, I got a density map as following : [?? ???????] When I set the level as 0.01, the density map as following: [?? ???????] So my question is that, does level 0.03 or 0.01 means, all grids with a density value lower than 0.03 or 0.01 will be present? Means when I set the level as 0.01, everything left in the density map is the density value lower than 0.01? Best, Tianming
