Binette 1.0.3

Binette
Binette is a fast and accurate binning refinement tool to constructs high quality MAGs from the output of multiple binning tools.
From the input bin sets, Binette constructs new hybrid bins. A bin can be seen as a set of contigs. When at least two bins overlap, meaning they share at least one contig, Binette utilizes basic set operations to create new bins.

Intersection bin: This bin consists of the contigs that are shared by the overlapping bins.
Difference bin: This bin contains the contigs that are exclusively found in one bin and not present in the others.
Union bin: The union bin includes all the contigs contained within the overlapping bins

It then uses CheckM2 to assess bins quality to finally select the best bins possible.
Binette is inspired from the metaWRAP bin-refinement tool but it effectively solves all the problems from that very tool.

Enhanced Speed: Binette significantly improves the speed of the refinement process. It achieves this by launching the initial steps of CheckM2, such as Prodigal and Diamond runs, only once on all contigs. These intermediate results are then utilized to assess the quality of any given bin, eliminating redundant computations and accelerating the refinement process.
No Limit on Input Bin Sets: Unlike its predecessor, Binette is not constrained by the number of input bin sets. It can handle and process multiple bin sets simultaneously.

Installation
With Bioconda
Binette can be easilly installed with conda
conda create -c bioconda -c defaults -c conda-forge -n binette binette
conda activate binette

Binette should be able to run :
binette -h

From a conda environnement
Clone this repository:
git clone https://github.com/genotoul-bioinfo/Binette
cd Binette

Then create a Conda environment using the binette.yaml file:
conda env create -n binette -f binette.yaml
conda activate binette

Finally install Binette with pip
pip install .

Binette should be able to run :
binette -h

Downloading the CheckM2 database
Before using Binette, it is necessary to download the CheckM2 database:
checkm2 database --download --path <checkm2/database/>

Make sure to replace <checkm2/database/> with the desired path where you want to store the CheckM2 database.
Usage
Input Formats
Binette supports two input formats for bin sets:

Contig2bin Tables: You can provide bin sets using contig2bin tables, which establish the relationship between each contig and its corresponding bin. In this format, you need to specify the --contig2bin_tables argument.

For example, consider the following two contig2bin_tables:


bin_set1.tsv:
contig_1 binA
contig_8 binA
contig_15 binB
contig_9 binC



bin_set2.tsv:
contig_1 bin.0
contig_8 bin.0
contig_15 bin.1
contig_9 bin.2
contig_10 bin.0

The binette command to process this input would be:
binette --contig2bin_tables bin_set1.tsv bin_set2.tsv --contigs assembly.fasta





Bin Directories: Alternatively, you can use bin directories, where each bin is represented by a separate FASTA file. For this format, you need to provide the --bin_dirs argument. Here's an example of two bin directories:
bin_set1/
├── binA.fa: contains sequences of contig_1, contig_8
├── binB.fa: contains sequences of contig_15
└── binC.fa: contains sequences of contig_9

bin_set2/
├── binA.fa: contains sequences of contig_1, contig_8, contig_10
├── binB.fa: contains sequences of contig_15
└── binC.fa: contains sequences of contig_9

The binette command to process this input would be:
binette --bin_dirs bin_set1 bin_set2 --contigs assembly.fasta



In both formats, the --contigs argument should specify a FASTA file containing all the contigs found in the bins. Typically, this file would be the assembly FASTA file used to generate the bins. In these exemple the assembly.fasta file should contain at least the five contigs mentioned in the contig2bin_tables files or in the bin fasta files: contig_1, contig_8, contig_15, contig_9, and contig_10.
Outputs
Binette results are stored in the results directory. You can specify a different directory using the --outdir option.
In this directory you will find:

final_bins_quality_reports.tsv: This is a TSV (tab-separated values) file containing quality information about the final selected bins.
final_bins/: This directory stores all the selected bins in fasta format.
input_bins_quality_reports/: A directory storing quality reports for the input bin sets, with files following the same structure as final_bins_quality_reports.tsv.
temporary_files/: This directory contains intermediate files. If you choose to use the --resume option, Binette will utilize files in this directory to prevent the recomputation of time-consuming steps.

The final_bins_quality_reports.tsv file contains the following columns:



Column Name
Description




bin_id
This column displays the unique ID of the bin.


origin
Indicates the source or origin of the bin, specifying from which bin set it originates or the intermediate set operation that created it.


name
The name of the bin.


completeness
The completeness of the bin, determined by CheckM2.


contamination
The contamination of the bin, determined by CheckM2.


score
This column displays the computed score, which is calculated as: completeness - contamination * weight. You can customize the contamination weight using the --contamination_weight option.


size
Represents the size of the bin in nucleotides.


N50
Displays the N50 of the bin.


contig_count
The number of contigs contained within the bin.
