MPA: A multiple peak alignment algorithm to perform multiple comparisons of liquid‐phase proteomic profiles

Present proteomic studies increasingly address experimental strategies focused on multiple comparisons of proteomic profiles. To accomplish semiautomatic protein separations based on 2-D LC, the Beckman Coulter PF2D has been developed. Here, we present a novel general purpose tool called MPA (multiple peak alignment) able to perform multiple comparisons of proteomic profiles both in a pairwise guided fashion and in a fully automatic mode using a strategy based on dynamic programing and progressive alignment of time series. The tool is available at http://grup.cribi.unipd.it/people/stefano/mpa/.
