%description
This toolkit is designed for manipulation and analysis of peptides. It
provides functionalities to assist researchers in peptide engineering and
proteomics. Users can manipulate peptides by adding amino acids at every
position, count occurrences of each amino acid at each position, and
transform amino acid counts based on probabilities. The package offers
functionalities to select the best versus the worst peptides and analyze
these peptides, which includes counting specific residues, reducing
peptide sequences, extracting features through One Hot Encoding (OHE), and
utilizing Quantitative Structure-Activity Relationship (QSAR) properties
(based in the package 'Peptides' by Osorio et al. (2015)
<doi:10.32614/RJ-2015-001>). This package is intended for both researchers
and bioinformatics enthusiasts working on peptide-based projects,
especially for their use with machine learning.
