I tracked the code and seems there are empty values for the users from 113-279. All values are like this [] when you import data from (.mat) files 

 

Could you please help me to get out of this error?

Hi @ala,

 

Thanks for tracing it. There was a bug caused by the channels with no available paths. It is fixed now in the current version.

For these channels with no available paths, a channel of all zeroes is returned.

Please re-download and try generating this.

 

Regards,

Umut

Thank you, Umut for solving it.

 

It is working well now. However, I believe you missed to remove this line (params.dataset_folder = 'C:\Users\Umt\Desktop\scenarios';) in the Parameter and defulat_parameter files. 

 

Many thanks,

Thanks for letting me know, I'll remove that. You can use that if you wish.
