AAComposition module¶
The module is used for computing the composition of amino acids, dipetide and
3-mers (tri-peptide) for a given protein sequence. You can get 8420 descriptors
for a given protein sequence. You can freely use and distribute it. If you hava
any problem, you could contact with us timely!
