A Python package to calculate, visualize and analyze correlation maps of proteins.

correlationplus contains four main scripts that you can use to calculate, visualize and analyze correlation maps of proteins. These correlations can be dynamical cross-correlations, linear mutual information, sequence based covariation/coevolution or any other pairwise coupling metric. You can use elastic network models or your molecular dynamics trajectories for calculation of dynamical correlations.

We recommend one of the installation methods for regular users:

conda install -c bioconda correlationplus

The pip version required by some dependencies is >= 21.0.1, which is not the pip version bundle with python 3.(6,7,8) So, you have to update pip before installing correlationplus. Otherwise, you will have trouble during MDAnalysis dependency installation. For this reason, we strongly encourage you to install correlationplus in a virtualenv.

python3 -m venv correlationplus
cd correlationplus
source bin/activate
python3 -m pip install -U pip
python3 -m pip install correlationplus

if you want to install it without using a virtualenv and encounter an error related to llvmlite, you can solve it as follows:

python3 -m pip install llvmlite --ignore-installed
python3 -m pip install correlationplus

or if you do not have administration rights

python3 -m pip install --user llvmlite --ignore-installed
python3 -m pip install --user correlationplus

Most of the time, at least one these methods will be sufficient for the installation. However, if these two methods didn't work for any reason, you can take a look to 'Advanced Installation' instructions at https://correlationplus.readthedocs.io/en/latest/installation.html#advanced-installation.

There are four main scrips:

• calculate
• visualize
• analyze
• paths

You can find details of each script with the following commands:

correlationplus calculate -h
correlationplus visualize -h
correlationplus analyze -h
correlationplus paths -h

Go to our readthedocs for detailed usage examples for each script.
