# Model Marketplace

The Model Marketplace allows members of the SAS Community to contribute plug-in fitting models for SasView for all to use.

Note

These plug-in models require SasView version 4.0 or later. However, not all models may work with every version of SasView because of changes to our API.

Contributed models should be written in Python (only version 2.7.x is currently supported) or, if computational speed is an issue, in a combination of Python and C. You only need to upload the .py/.c source code files to the Marketplace!

Please put a comment in your code to indicate which version of SasView you wrote the model for.

For guidance on how to write a plugin model see Writing a Plugin Model . It may also be helpful to examine the library models in the /sasmodels-data/models sub-folder of your SasView installation directory.

The Marketplace also provides the option to upload a SasView text file of the scattering function data computed by your model. If you do this a graph of the scattering function will appear under the Marketplace entry for your model.

Note

The SasView Development Team regret to say that they do not have the resources to fix the bugs or polish the code in every model contributed to the Marketplace!
