-PanACOTA is a software providing tools for large scale bacterial comparative  genomics. From a set of complete and/or draft genomes, you can:
-
-   -  Do a quality control of your strains, to eliminate poor quality genomes, which would not give any information for the comparative study
-   -  Uniformly annotate all genomes
-   -  Do a Pan-genome
-   -  Do a Core or Persistent genome
-   -  Align all Core/Persistent families
-   -  Infer a phylogenetic tree from the Core/Persistent families
