The following amyloid predictor works on hexapeptides, i.e., six amino acid long sequences. You need to input exactly six capital letters from the one-letter codes of the 20 amino acids: A,C, D, E, F, G, H, I, K, L, M, N, P, Q, R, S, T, V, W, Y, for example “IVVIVV”. The tool returns the prediction for the query, plus for the radius-1 environment, i.e., for all 114 hexapeptides, which differ only in one letter from your query.
The prediction is made by a Support Vector Machine (SVM), trained and tested on the Waltz hexapeptide data set, its accuracy is 84%. For detailed information, see the article:
