To use the classifier to predict blood-brain barrier permeability for peptides, either:

• paste your raw peptides string into the text area, or
• upload a text-formatted file with your peptide; or
• the sequences shorter than 3aa or longer than 50aa are not recommended for evaluation.

Press the "Reset" button to clear the input and re-enter.
Press the "Submit" button to upload the SMILES and begin the classification.
Waiting a moment and your results will be presented in web page.
