Supplementary data are available at Bioinformatics online. Direct coupling analysis (DCA) infers coevolutionary couplings between pairs of residues indicating their spatial proximity, making such information a valuable input for subsequent structure prediction. This made it possible to study the patterns of correlated substitution between residues in families of homologous proteins or RNAs and to retrieve structural and stability information.

The command pydca is used for tasks such as trimming alignment data before DCA computation, and Here, we present pydca, a standalone Python-based software package for the DCA of protein- and RNA-homologous families. NLM When pydca is installed, it provides three main command.

It is based on two popular inverse statistical approaches, namely, the mean-field and the pseudo-likelihood maximization and is equipped with a series of functionalities that range from multiple sequence alignment trimming to contact map visualization. DCA computation with the pseudolikelihood maximization algorithm (plmDCA) or the mean-field algorithm (mfDCA). This made it possible to study the patterns of correlated substitution between residues in families of homologous proteins or RNAs and to retrieve structural and stability information.

PyFeat: a Python-based effective feature generation tool for DNA, RNA and protein sequences. We present the EVcouplings framework, a fully integrated open-source application and Python package for coevolutionary analysis. Results: Trim by percentage of gaps in MSA columns: We can also the values of regularization parameters. PyPSA is a free software toolbox for simulating and optimising modern power systems that include features such as conventional generators with unit commitment, variable wind and solar generation, storage units, coupling to other energy sectors, and mixed alternating and direct current networks. The command compute_fn computes DCA scores obtained from the Frobenius norm of the couplings. pydca is Python implementation of direct coupling analysis (DCA) of residue coevolution for protein and RNA sequence families using the mean-field and pseudolikelihood maximization algorithms. Direct coupling analysis (DCA) infers coevolutionary couplings between pairs of residues indicating their spatial proximity, making such information a valuable input for subsequent structure prediction. To get help message about a (sub)command we use, for example, Zerihun, MB., Pucci, F, Peter, EK, and Schug, A. pydca can be obtained from https://github.com/KIT-MBS/pydca or from the Python Package Index under the MIT License. pydca is implemented mainly in Python with the pseudolikelihood maximization parameter inference part implemented using C++ backend for optimization.
