Classifies the protein fold by combing the results from two algorithms, HH-fold and support vector machines (SVM)-fold. TA-fold is an ensemble approach proposed to combine the results of these algorithms. HH-fold is a template-based fold assignment algorithm using the Hidden Markov Model (HMM)-HMM alignment program HHsearch. SVM-fold is a support vector machine-based ab-initio classification algorithm. When there are homologous templates to the query protein, HH-fold prediction is reported. Otherwise, the SVM-fold prediction is returned.
