Processing multiple datasets using Topas

Refining multiple datasets can have several advantages; Firstly, it allows for some automation e.g. a sequence of potentially hundreds of datasets can be refined in sequence automatically. Secondly, you can refine parameters over multiple datasets, reducing the error in the parameter over a larger sample. Thirdly you can refine other parameters with temperature etc.

There are several ways to achieve this using Topas. This tutorial is designed to give a flavour of what can be done by using simple examples which the user can base their own refinement setup on. It is in several stages, as can be seen in the schematic below. Each tutorial builds in complexity.

The tutorial instructions can be found
here, as a PDF. This is the  "quick start guide". More detailed information can be found in the word document which is included with the datafiles and can be downloaded here.
