Introduction
FlexSA is a flexible system for sequence analysis. It contains three parts: a graphic interface, a training program and a decoding program. The graphic interface allows users to create a system model (modular) by drawing a diagram, and it will create the training and decoding program for the sequence model. Currently, generalized hidden markov model (GHMM) framework is supported by FlexSA.
