RF validation/OOB

Would anybody be able to tell me how OOB (out-of-bag error) is retrieved from RF classification in SNAP? Is it calculated automatically?
Many thanks

out-of-bag error is well explained in here,

Thanks @falahfakhri :slight_smile:
I was wondering is SNAP calculates it, and if is so where is it shown-is it the cross-validation file produce after classifying?

I think it’s calculated inclusively, but the report of RFC gives only the accuracy, please have a look at this thread,
