I am trying to use the Pearl and necklace model from the Sasview. I am unable to use the this model. When trying to fit my data using this model goodness of fit is always showing the error (Nan). (Fit also did not converge for any value of parameters) Can you please suggest what may be the problem?

Likely the parameters you are starting with are not good enough and/or your data does not fit the model. Could you send a graph of the data and model with the parameters you are starting with?
