Counting BioSequences' atoms
This is a fast and lightweight package that counts the number of atoms in a given
BioSequenceobject. It was inspired by the Biocost.jl package.
BioAtomsCount is a
pkg> add BioAtomsCountThe BioAtomsCount module exports a single function countatoms which takes a BioSequence object as input and returns a matrix of the count of atoms in the sequence.
Each column of the matrix corresponds to a different atom (C, H, N, O) for DNA and (C, H, N, O, S) for proteins and each row corresponds to a different residue in the sequence.
Here is an example of a DNA sequence:
