Hello,

I hope you are well. I am currently trying to build a reasonably complex model within sasview and have gone to the guide on how to manage this. I see in the documentation (SasView-6.1.3/sas/docs/user/qtgui/Perspectives/Fitting/fitting_help.html) that to achieve this one creates a 'simple' model combining two established models, then opens the model in the model editor. One can then add/multiply several different functions together by editing the text after 'load_model_info'.

My question is how do I account for multiplying several summed models by a single other model, as brackets seemingly cannot be used. AKA how do I achieve the following sort of functions:

(sphere + gaussian_peak + sphere)*user_defined_fractal_model

((sphere + gaussian_peak) + sphere)*user_defined_fractal_model

((sphere  + sphere)*user_defined_fractal_model) + gaussian_peak

Any insight you have would be extremely helpful. Thank you so much.

All the best,

Harrison Laurent
