BUSCO completeness assessments employ sets of Benchmarking Universal Single-Copy Orthologs from OrthoDB ( to provide quantitative measures of the completeness of genome assemblies, annotated gene sets, and transcriptomes in terms of expected gene content.


Important Notes

Interactive job
Interactive jobs should be used for debugging, graphics, or applications that cannot be run as batch jobs.

Allocate an interactive session and run the program.
Sample session (user input in bold):

[user@biowulf]$ sinteractive
salloc.exe: Pending job allocation 46116226
salloc.exe: job 46116226 queued and waiting for resources
salloc.exe: job 46116226 has been allocated resources
salloc.exe: Granted job allocation 46116226
salloc.exe: Waiting for resource configuration
salloc.exe: Nodes cn3144 are ready for job

[user@cn3144 ~]$ module load busco
[+] Loading busco  3.0.2
Busco Config file /home/user/busco.config  does not exist

   copying from /usr/local/apps/busco/Augustus/config

#####Edit the busco.config file to set any additional parameters desired

[user@cn3144 ~]$ nano ~/busco.config

##### Download and unpack the required lineage-specific profile library.
[user@cn3144 ~]$ wget
[user@cn3144 ~]$ tar xvzf bacteria_odb9.tar.gz

##### Copy the sample data set 

[user@cn3144 ~]$ cp -r /usr/local/apps/busco/sample_data  .
[user@cn3144 ~]$ cd sample_data

##### Run BUSCO
[user@cn3144 ~]$ -i target.fa -i target.fa -o test -l ../bacteria_odb9/ -m geno

Batch job
Most jobs should be run as batch jobs.

Create a batch input file (e.g. The example below assumes that you have downloaded the lineage-specific profile library and edited the BUSCO config as desired.

set -e
module load busco  -i target.fa -o test -l ../bacteria_odb9/ -m geno

Submit this job using the Slurm sbatch command.
