Given a cif file and gsa data file, automatically get best-fit structure.

The scriptable GSAS-II engine used here for fitting powder patterns can ONLY process properly structures with origin choice 2. Please make sure your uploaded structure is with proper choice of origin.

Without interface to the varieties of control for the powder pattern fitting, current web interface is ONLY providing preliminary fittings.

In the result page, one can download the GSAS-II project to perform further fine tuning of the refinement locally and interactively with GSAS-II.
