Molecular nodes

Hi

I have a question regarding the selection of a combination of objects. I work in science, performing molecular dynamic simulation. Since recently a add-on for importing pdb and trajectory files are available I can produce very nice simulations of proteins moving around a fix space of waters. However, when I import the pdb file (protein) and its trajectory over time (dcd) I only see the waters since they are blocking the view of the protein which is inside. Is there any way to select only the waters, even though is one by one, and delete them? This is a snapshot of the 1st frame of the simulation. Thanks a lot!

The project explorer has option to disable the selectable option. Other things you could do put them on different layer groups so you switch between them, or hide (H) one. If for visually you can create custom shaders And with geometry nodes nearby tricks you could remove nearby particles. Perhaps a better place to call for help is blender stackoverflow
