Hi,

I understand that you are facing issues while classification to extract features.
It seems that you are encountering this issue because you are using the variable name 'scatter' to access a position within an array. Since 'scatter' can be either a function or a variable, this is causing the problem. To resolve it, I recommend using integer indices to access the desired elements within the arrays.
Hope it helps!
