Can't select all side chains for 3JC8

Ha, I have already missed my thesis deadlines because I've been developing this project instead, so you'll be in good company!

Re: the MOL_style_manual_colour node, you need to have a material applied, so either unmute the previous MOL_style_colour node or use a "Set Material" node afterwards to apply the molecular material and it should work!

The Atoms EEVEE node is a bit buggy, it doesn't do individual chain colouring above about 10 or so chains. This is due to some underlying problems with how it's executed, and I just haven't put in the time to make it more robust to handle more chains.

I recommend if possible to use the regular cycles atoms, if you need the per-chain colouring, or use ribbon or surface style for more chains with different colours.

For the kind of per-chain colouring that you are doing as well, you can use the Style Colour Manual node which lets you colour based on a selection, rather than having to split apart and then join back together:

It seems to be a blender-related bug that is causing the atoms to lose colour when they are split apart and joined back together, it's something that I haven't been able to solve myself. A workaround is to use the "Geometry to Instance" node on one of them before joining them back together to maintain the colour.

Thanks for getting back to me so quickly. Indeed both solutions work: using ribbon/surface I can style more chains or using the Cycles atoms styles I can also do the same.
However while MOL_style_color lets me apply the color, MOL_style_manual_color doesn't:

Anyway this solution works for me, thank you!

With a bit of work I can color all the chains

Molecular nodes is more fun than it ought to be, if I don't meet my PhD thesis deadline I will hold you personally responsible :)
