Hi,
I’m fairly new to ChimeraX so forgive me if I’m a bit ignorant in this question.
I have volumes acquired by tomographic reconstruction of STEM/EDS data (elemental composition in an electron microscope). I want to visualize several elements together as different colors representing phases. In some cases, the boundary is fairly obvious and can be represented with an isosurface.
When I try to set the transparency of the isosurface so I can see the objects inside it, it simply turns darker color rather than transparent. As an example, here is a silicon isosurface obscuring the other volumes inside it:
I’m setting the transparency using the colors dialog box:
For comparison, if I make the isosurface invisible to show the objects inside:
If instead I use the transparency command:
volume #5 transparency 50
The isosurface turns black:
My question is: am I doing this incorrectly?
Thanks,
