BUSCO

BUSCO (pour Benchmarking Universal Single-Copy Orthologs) est une application qui permet d'évaluer la complétude de l'assemblage et de l'annotation de génomes.

Pour plus d'information, consultez le manuel de l'utilisateur.

Versions disponibles

Les versions récentes sont disponibles dans des wheels et les plus anciennes versions sont dans un module (voir la section Modules ci-dessous).

Pour connaître la dernière version disponible, lancez

[name@server ~]$ avail_wheel busco

Wheel Python

Installation

1. Chargez les modules requis.

[name@server ~]$ module load StdEnv/2020 gcc python/3.10 augustus hmmer blast+ metaeuk prodigal r bbmap

2. Créez l'environnement virtuel.

[name@server ~]$ virtualenv ~/busco_env
[name@server ~]$ source ~/busco_env/bin/activate

3. Installez le wheel et ses dépendances.

(busco_env) $ pip install biopython pandas busco --no-index

[name@server ~]$ export BUSCO_CONFIG_FILE=$HOME/busco_config.ini
[name@server ~]$ export AUGUSTUS_CONFIG_PATH=$HOME/augustus_config
[name@server ~]$ run_BUSCO.py --in $EBROOTBUSCO/sample_data/target.fa --out TEST --lineage_path $EBROOTBUSCO/sample_data/example --mode genome

Test

4. Téléchargez les données de test:

[name@server ~]$ wget https://gitlab.com/ezlab/busco/-/raw/master/test_data/bacteria/genome.fna
[name@server ~]$ wget https://busco-data.ezlab.org/v5/data/lineages/bacteria_odb10.2020-03-06.tar.gz

5. Lancez la commande

[name@server ~]$ busco --offline --in genome.fna --out TEST --lineage_dataset bacteria_odb10 --mode genome --cpu ${SLURM_CPUS_PER_TASK-1}

You can access the available datasets in your terminal by typing busco --list-datasets.

You have two options to download datasets:

• use the busco command,
• use the wget command.

6.1 Using the busco command

This is the preferred option. Type this command in your working directory to download a particular dataset, for example

[name@server ~]$ busco --download bacteria_odb10

It is also possible to do a bulk download by replacing the dataset name by the following arguments: all, prokaryota, eukaryota, or virus, for example

[name@server ~]$ busco --download virus

The hierarchy will look like this:

• busco_downloads/

• information/

lineages_list.2021-12-14.txt

• lineages/

bacteria_odb10

actinobacteria_class_odb10

actinobacteria_phylum_odb10

• placement_files/

list_of_reference_markers.archaea_odb10.2019-12-16.txt

Doing so, all your lineage files should be in busco_downloads/lineages/. When referring to --download_path busco_downloads/ in the BUSCO command line, it will know where to find the lineage dataset argument --lineage_dataset bacteria_odb10. If the busco_download directory is not in your working directory, you will need to provide the full path.

6.2 Using the wget command

All files must be decompressed with tar -xvf file.tar.gz.

[name@server ~]$ mkdir -p busco_downloads/lineages
[name@server ~]$ cd busco_downloads/lineages
[name@server ~]$ wget https://busco-data.ezlab.org/v5/data/lineages/bacteria_odb10.2020-03-06.tar.gz
[name@server ~]$ tar -xvf bacteria_odb10.2020-03-06.tar.gz

4. Copiez le répertoire de configuration d’Augustus à un endroit accessible en écriture.

[name@server ~]$ cp -r $EBROOTAUGUSTUS/config $HOME/augustus_config

[name@server ~]$ wget https://gitlab.com/ezlab/busco/-/raw/master/test_data/bacteria/genome.fna

Dépannage

Message Cannot write to Augustus config path

Vérifiez que le fichier de configuration se trouve à un endroit accessible en écriture et que la variable AUGUSTUS_CONFIG_PATH a bien été définie.

Command to run a single genome:

[name@server ~]$ busco --offline --in genome.fna --out TEST --lineage_dataset bacteria_odb10 --mode genome --cpu ${SLURM_CPUS_PER_TASK:-1} --download_path busco_download/

Command to run multiple genomes that would be saved in the genome directory (in this example, the genome/ folder would need to be in the current directory; otherwise, you need to provide the full path):

[name@server ~]$ busco --offline --in genome/ --out TEST --lineage_dataset bacteria_odb10 --mode genome --cpu ${SLURM_CPUS_PER_TASK:-1} --download_path busco_download/

Cette commande devrait prendre moins de 60 secondes. Les tâches dont la production est plus longue doivent être soumises à l'ordonnanceur.

Versions disponibles

Les versions récentes sont disponibles dans des wheels et la plus ancienne version dans un module (voir la section Modules ci-dessous).

Specify --in genome.fna for single file analysis.

Specify --in genome/ for multiple files analysis.

La version 3.0.2 est un module sur cvmfs et accessible sur toutes les grappes; les renseignements sur comment l'utiliser sont montrés ci-dessous. Il est possible d'installer localement les versions plus récentes en utilisant un environnement virtuel comme suit :

[name@server ~]$ ~ $ module load python/3.7.4
~ $ git clone https://gitlab.com/ezlab/busco.git
~ $ virtualenv /home/$USER/busco_env
~ $ source /home/$USER/busco_env/bin/activate
(busco_env) [~]$ pip install Biopython
(busco_env) [~]$ cd ~/busco
(busco_env) [~]$ python setup.py install
(busco_env) [~]$ cp -r scripts test_data /home/$USER/busco_env/

et ajoutez home/$USER/busco_env/scripts au chemin.

Sounmettre une tâche

Here you have an example of a submission script. You can submit as so: sbatch run_busco.sh.

File : run_busco.sh

#!/bin/bash

#SBATCH --job-name=busco9_run
#SBATCH --account=def-someprof    # adjust this to match the accounting group you are using to submit jobs
#SBATCH --time=01:00:00           # adjust this to match the walltime of your job
#SBATCH --cpus-per-task=8         # adjust depending on the size of the genome(s)/protein(s)/transcriptome(s)
#SBATCH --mem=20G                 # adjust this according to the memory you need

# Load modules dependencies.
module load StdEnv/2020 gcc python augustus hmmer blast+ metaeuk prodigal r bbmap

# Generate your virtual environment in $SLURM_TMPDIR.
virtualenv --no-download ${SLURM_TMPDIR}/env
source ${SLURM_TMPDIR}/env/bin/activate

# Install busco and its dependencies.
pip install --no-index --upgrade pip
pip install --no-index --requirement ~/busco-requirements.txt

# Edit with the proper arguments, run your commands.
busco --offline --in genome.fna --out TEST --lineage_dataset bacteria_odb10 --mode genome --cpu ${SLURM_CPUS_PER_TASK:-1} --download_path busco_download/

Augustus parameters

9. Advanced users may want to use Augustus parameters: --augustus_parameters="--yourAugustusParameter".

• Copy the Augustus config directory to a writable location.

[name@server ~]$ cp -r $EBROOTAUGUSTUS/config $HOME/augustus_config

• Make sure to define the AUGUSTUS_CONFIG_PATH environment variable.

[name@server ~]$ export AUGUSTUS_CONFIG_PATH=$HOME/augustus_config

SEPP parameters

10. To use SEPP parameters, you need to install SEPP locally in your virtual environment. This should be done in a login node.

10.1. Activate your BUSCO virtual environment.

[name@server ~]$ source busco_env/bin/activate

10.2. Install DendroPy.

[name@server ~]$ pip install 'dendropy<4.6'

10.3. Install SEPP.

[name@server ~]$ git clone https://github.com/smirarab/sepp.git
[name@server ~]$ cd sepp
[name@server ~]$ python setup.py config
[name@server ~]$ python setup.py install

10.4. Validate the installation.

[name@server ~]$ cd
[name@server ~]$ run_sepp.py -h

10.5. Because SEPP is installed locally, you cannot create the virtual environment as described in the previous submission script. To activate your local virtual environment, simply add the following command immediately under the line to load the module:

[name@server ~]$ source ~/busco_env/bin/activate

Modules

Deprecation

This section is outdated. We are currently working on an update.

1. Chargez les modules nécessaires.

[name@server ~]$ module load StdEnv/2018.3 gcc/7.3.0 openmpi/3.1.4 busco/3.0.2 r/4.0.2

Ceci charge aussi les modules pour augustus, blast+, hmmer et d'autres paquets requis par BUSCO.

La commande run_BUSCO.py devrait prendre moins de 60 secondes. Les tâches dont la production est plus longue doivent être soumises à l'ordonnanceur.

Pour plus d’information, consultez le manuel d'utilisation.
