Pseudo-counts distributed in an equiprobable waydistributed proportionally to residues priors

Background model estimation method

    Markov order     High orders can be time-consuming, but order 0 is generally not representative. We recommend orders 1 or 2.


      Genomes in the RSAT Prokaryotes server were recently re-installed. Genome names now follow the NCBI standard to easily identify assemblies, if you cannot find your genome please check this naming list to find the correct ID: Genome IDs list
