Binning using CCOM

As an alternative to manual binning using crAss, and using metabat, we have developed a website, Contig Clustering of Metagenomes where you can upload reads and contigs, and we will run three different binning algorithms: metabat, GroopM and crAss.

The input files for CCOM require a contig file that has to have .fasta extension, and all the individual read files used as input to form the contig. For example for the algae data, we have the contigs.fasta file, and all the individual reads files Algae_11.renum.fna, Algae_12.renum.fna, Algae_13.renum.fna, Algae_14.renum.fna files.

Note: The extension of the read files must be changed from .fasta to .fna, this doesn’t change the file format but allows the CCOM tool recognize the reads file from the contig file. Only one set can be run at a time (i.e. you can not run multiple contig files at the same time), but you can upload several independent datasets and wait for them to be processed..

The output from CCOM is saved in a zip file called workfile.zip that you can download.

Unzip the file and navigate to /workfile/var/www/html/ContigClustering/cgi-bin/ContigClustering/uploads/XXXXXXXX. The XXXXXXXX will be a Job ID number that is created by CCOM and is unique to you. This file contains all the temporary files (.bam, .bai and .sam files) generated while running the binning tools. The bins extracted from the contigs are saved in the the folders: MetaBatBins, GroopMBins.
