How to Determine the Unit Cell Type From the XRD Data?

In summary, Tom is seeking help in determining the density of his sample by finding the lattice parameters through XRD data. He is unsure of the crystallographic system and is looking for a way to determine the type of unit cell his sample has. He mentions using GSAS II and asks for a good source to study this topic, as the textbook he has and a Google search have not been helpful. He then shares a link he found through a quick Google search and suggests trying a scholar search for more reliable sources.

Hey guys,

I got an XRD data for my sample and want to determine its density. This requires finding lattice parameters. However, I'm not certain about the crystallographic system of my sample. How can I determine the type of the unit cell my sample has from XRD data (I can use GSAS II if needed)? Do you know a good source where I can study this?

Textbook I have (X-Ray Diffraction from Warren) doesn't explain it very clearly to me and Google search didn't give the good sources.
