How to create particles in a existing datacollection?

Hi Ovito developers,

I have calculated the position of center of mass of some molecules and I want to add them into an existing data collection as fake atoms. Because I want to process this data later. Is this possible in ovito and how to make it?

Wish to get your reply. Thanks

Depending on the number of centers you need to load into OVITO, you can either:

  1. Export them as a file (e.g., .xyz) and load them into OVITO as either a secondary pipeline or using the combine datasets modifier.
  2. Alternatively, use the add_particles Python method.

Thanks for your reply. First method should work for me.
