GitHub repository for the manuscript "MetaBinner: a high-performance and stand-alone ensemble binning method to recover individual genomes from complex microbial communities". We are glad that Metabinner achieves top performance on the CAMI II Challenge overall. Please refer to Meyer, F. et al. [1] for the results of the CAMI II Challenge.
MetaBinner consists of two modules: 1) “Component module” includes steps 1-4, developed for generating high-quality, diverse component binning results; and 2) “Ensemble module” includes step 5, developed for recovering individual genomes from the component binning results. MetaBinner is an ensemble binning method, but it does not need the outputs of other individual binners. Instead, MetaBinner generates multiple high-quality component binning results based on the proposed “partial seed” method for further integration. Please see our manuscript for details.
conda create -n metabinner_env python=3.7.6conda activate metabinner_env
conda install -c bioconda metabinnerObtain codes and create an environment: After installing Anaconda (or miniconda), first obtain MetaBinner:
git clone https://github.com/ziyewang/MetaBinner.gitThen simply create an environment to run MetaBinner.
cd MetaBinner
conda env create -f metabinner_env.yaml
conda activate metabinner_envMetaBinner is supported and tested in Linux systems.
The preprocessing steps aim to generate coverage and composition profiles as input to our program.
Several binning methods can generate these two types of information (such as CONCOCT and MetaWRAP), and we provide one way to generate the input files as follows.
The coverage profiles of the contigs for the results in the manuscript were obtained via MetaWRAP 1.2.1 script: ``binning.sh".
If users have obtained the coverage (depth) file generated for MaxBin (mb2_master_depth.txt) using MetaWRAP, they can run the following command to generate the input coverage file for MetaBinner:
cat mb2_master_depth.txt | cut -f -1,4- > coverage_profile.tsvor remove the contigs no longer than 1000bp like this:
cat mb2_master_depth.txt | awk '{if ($2>1000) print $0 }' | cut -f -1,4- > coverage_profile_f1k.tsv
To generate coverage from sequencing reads directly, run the following script slightly modified from the "binning.sh" of MetaWRAP. The script supports different types of sequencing reads, and the default type is "paired" ([readsX_1.fastq readsX_2.fastq ...]). If MetaBinner is installed via bioconda, users can obtain path_to_MetaBinner via running this command:
cd path_to_MetaBinner
cd scripts
bash gen_coverage_file.sh -a contig_file \
-o output_dir_of_coveragefile \
path_to_sequencing_reads/*fastq
Options:
-a STR metagenomic assembly file
-o STR output directory (to save the coverage files)
-b STR directory for the bam files (optional)
-t INT number of threads (default=1)
-m INT amount of RAM available (default=4)
-l INT minimum contig length to bin (default=1000bp).
--single-end non-paired reads mode (provide *.fastq files)
--interleaved input read files contain interleaved paired-end reads
-f Forward read suffix for paired reads (default="_1.fastq")
-r Reverse read suffix for paired reads (default="_2.fastq")
Composition profile is the vector representation of contigs, and we use kmer (k=4 in the example) to generate this information. To generate the composition profile and keep the contigs longer than contig_length_threshold, such as 1000, for binning, run the script as follows:
cd path_to_MetaBinner
cd scripts
python gen_kmer.py test_data/final.contigs_f1k.fa 1000 4
Here we choose k=4. By default, we usually keep contigs longer than 1000; users can specify a different number. The kmer_file will be generated in the /path/to/contig_file.
And the users can run the following command to keep the contigs longer than 1000bp for binning.
cd path_to_MetaBinner
cd scripts
python Filter_tooshort.py test_data/final.contigs_f1k.fa 1000

#path to MetaBinner
metabinner_path=/home/wzy/MetaBinner
Note: If users install MetaBinner via bioconda, they can set metabinner_path as follows: metabinner_path=$(dirname $(which run_metabinner.sh))
##test data
#path to the input files for MetaBinner and the output dir:
contig_file=/home/wzy/MetaBinner/test_data/final_contigs_f1k.fa
output_dir=/home/wzy/MetaBinner/test_data/output
coverage_profiles=/home/wzy/MetaBinner/test_data/coverage_profile_f1k.tsv
kmer_profile=/home/wzy/MetaBinner/test_data/kmer_4_f1000.csv
bash run_metabinner.sh -a ${contig_file} -o ${output_dir} -d ${coverage_profiles} -k ${kmer_profile} -p ${metabinner_path}
Options:
-a STR metagenomic assembly file
-o STR output directory
-d STR coverage_profile.tsv; The coverage profiles, containing a table where each row corresponds
to a contig, and each column correspond to a sample. All values are separated with tabs.
-k STR kmer_profile.csv; The composition profiles, containing a table where each row corresponds to a contig,
and each column correspond to the kmer composition of a particular kmer. All values are separated with comma.
-p STR path to MetaBinner; e.g. /home/wzy/MetaBinner
-t INT number of threads (default=1)
-s STR Dataset scale; eg. small,large,huge (default:large); Users can choose "huge" to run MetaBinner on huge datasets
with lower memory requirements.
#The file "metabinner_result.tsv" in the "${output_dir}/metabinner_res" is the final output.
Note: all paths in the run_metabinner.sh options should be absolutePlease feel free to send bug reports or questions to Ziye Wang: [email protected] and Prof. Shanfeng Zhu: [email protected]
