Bin Pangenomes by Sequence

Binning by sequence is done irrespective of a database, only depending on content and coverage. To have both sources of information available, the Bin Pangenomes by Sequence tool takes read mappings to contigs as input, where there should be one read mapping per technical replicate (each mapping to the same contigs) in order to make most use of coverage information across all samples. However, if read mappings are not available, the Bin Pangenomes by Sequence tool also takes plain sequence lists of contigs as input.

The Bin Pangenomes by Sequence algorithm is based on the MetaBAT[Kang et al., 2015] and SCIMM[Kelley and Salzberg, 2010] algorithms with several modifications:

To start the tool, go to:

        Toolbox | Microbial Genomics Module (Image mgm_folder_closed_flat_16_h_p) | Metagenomics (Image wma_folder_open_flat_16_n_p) | Taxonomic Analysis (Image taxonomic_analysis_folder_closed_16_n_p) | Bin Pangenomes by Sequence (Image binpan_sequence_16_n_p)

The Bin Pangenomes by Sequence takes one sequence list of contigs or one read mapping per sample as input (figure 6.4).

In the next dialog (figure 6.5), the several parameters can be specified:

Finally, in the "Result handling" dialog, it may be specified whether the reads of the binned contigs should be labelled and collected.

The standard output of the Bin Pangenomes by Sequence tool consists of a Sequence binning report, a contig list with their assigned bin listed in the Assembly_ID column, and as many read lists as read mappings were used as input in the tool, where reads have been assigned the bin of the contig they belong to.
