Hi, all~

I would like to ask the way how to choose a certain number of molecules among the many same molecules.

For example, in MD simulation of fuel cell membrane under hydrated state, there are many water molecules within 3D cell.

In this case, if I want to delete all the water molecules, I can do this work easily with atom selection tab.

Then, I can choose all the water molecules and remove them at a time.

However, if I want to remove a half of the water molecules (ex. to remove only 50 water molecules of total 100 water molecules), there seems to be no function for this in Material Studio.

Could you please give me an advice for this?

Best regards
