How to understand the output of the code SYNAPPS?

[amitkundupabra]

After successfully running the code SYNAPPS, where do I get the best fit values of opacity, temperature and other parameters? What does 'f' and 'x' in cache file mean as shown below?

Dear Sir, I also have an another issue, I am running code SYNAPPS on a set of online available spectra of type Ic SNe, the problem is that, most of available spectra are in form of wavelength and flux. Flux_err is not given.
So how can I apply SYNAPPS on these spectra ?
And is it necessary that our flux and Flux_err should be in normalised form?
