Antigenic: An improved prediction model of protective antigens.

•We present a new computational model to identify protective antigens in an efficient and accurate way.•We extract meaningful information directly from the protein sequences, without any dependence on functional domain or structural information.•Named as antigenic, our proposed model demonstrates superior performance compared to the state-of-the-art predictors on a benchmark dataset.•A publicly accessible web interface has been established at: http://77.68.43.135:8080/Antigenic/.
