Are there computational tools to extract features of DNA sequences? I am looking for tools to extract features from short DNA sequences. For example, entropy, complexity, GC-content, etc.
I have found the generateFeatures.py script from the PyFeat repo, but is there love a more widely used source code or a standard way to extract features from sequences biopython or similar?
Also, I think that since there are $2N$ encoded bits in a sequence of $N$ nucleotides, we have at most $2N$ independent features that could be extracted.

In addition, I am curios if there are any transformers models for DNA sequences.
If you want to do this with biopython, the SeqUtils package could be a solution.
