%description
Predicts anticancer peptides using random forests trained on the n-gram
encoded peptides. The implemented algorithm can be accessed from both the
command line and shiny-based GUI. The CancerGram model is too large for
CRAN and it has to be downloaded separately from the repository:
<https://github.com/BioGenies/CancerGramModel>. For more information see:
Burdukiewicz et al. (2020) <doi:10.3390/pharmaceutics12111045>.
