n fast core gene alignment with MAFFT, use with -e e create a multiFASTA alignment of core genes using PRANK It takes in GFF files and outputs various analysis. To run the software and create a pan genome you use the roary script. Just be aware that mixing different gene prediction methods and annotation pipelines can give noisier results.Īlternatively you can use ncbi-genome-download to pull down the FASTA files and convert them to GFF3 with Prokka. You can then use the Bio::Perl script bp_ to convert to GFF3.

You need to download the GenBank files plus nucleotide sequence and convert them. On NCBI's website, GFF3 files only contain annotation and not the nucleotide sequence so cannot be used. Each input file should have a unique locus tag for the gene IDs (-locustag) to make it easier for you to identify where genes came from. Input files from ProkkaĪll GFF3 files created by Prokka are valid with Roary and this is the recommended way of generating the input files.
They must contain the nucleotide sequence at the end of the file.

The Microbial Genomics Lab at CBIB have put together an excellent step by step tutorial on using Roary.ĭetails on how to install Roary. Keane, Julian Parkhill, "Roary: Rapid large-scale prokaryote pan genome analysis", Bioinformatics, 2015 31(22):3691-3693 doi:10.1093/bioinformatics/btv421 Step by step tutorial Holden, Maria Fookes, Daniel Falush, Jacqueline A. Citation and further details of the methodĪndrew J. Roary is not intended for meta-genomics or for comparing extremely diverse sets of genomes. To perform this analysis using existing methods would take weeks and hundreds of GB of RAM. 128 samples can be analysed in under 1 hour using 1 GB of RAM and a single processor. Using a standard desktop PC, it can analyse datasets with thousands of samples, something which is computationally infeasible with existing methods, without compromising the quality of the results. Roary is a high speed stand alone pan genome pipeline, which takes annotated assemblies in GFF3 format (produced by Prokka (Seemann, 2014)) and calculates the pan genome.
