Hello Alex,

There are two options in the LCF page that may help.  If you don’t want any negative values try selecting “All weights between 0 and 1” and unselecting “Force weights to sum to 1”.

Hello!

I faced an issue with 0.9.26 Athena. Doing LCF the option for weights doesn't really work so I keep getting negative components.

Cheers,

Alex
