Hello, I am not certain about the rule of Challenge Rules & Conditions. "An exception to this rule is the use of sequence features derived from DNA sequence. E.g. participants can use experimentally or computationally derived sequence motifs or other types of features derived from DNA sequence from any source." Can I use feathers derived from histone modification data in this challenge? I know I can not use the histone modification data in the prediction model, but how about use it as an upstream feather? Thanks
