OrthoMCL is a genome-scale algorithm for grouping orthologous protein sequences

User Guide

OrthoMCL uses a database to run its analyses. If you would like to use OrthoMCL on our servers, please send us an email and we’ll set up access to our database server for you.

After your database account is setup, you can configure OrthoMCL with a orthomcl.config file like this:


Once you have that set up, you can initialize the database using:

module load orthomcl
orthomclInstallSchema orthomcl.config

You can connect to your orthomcl database with:

mysql -u your_username -p --host=data-orthomcl.ibest.uidaho.edu -D your_username

You will then be prompted for your password

You can clear tables from your database by connecting, then running the DROP TABLE command. Use caution, as there is no way to recover a dropped table.

ibestadm@fortytwo ~ $ mysql -u ibestadm -p --host=data-orthomcl.ibest.uidaho.edu -D ibestadm
