The ongoing advances in sequencing technologies have provided a massive increase in the availability of sequence data. Here, we present pydca, a standalone Python-based software package for the DCA of protein- and RNA-homologous families. After installation, pydca can be imported into other Python source codes and used. RNA. This web page contains MATLAB-code (and accompanying C-written routines) for plmDCA. Namely pydca, plmdca, and mfdca. PNAS December 6, 2011 108 (49) E1293-E1301, doi:10.1073/pnas.1111471108, Ekeberg, M., Lövkvist, C., Lan, Y., Weigt, M., & Aurell, E. (2013).

Epub 2020 Apr 10. 2020 Nov 16;15(11):e0242072. 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. COVID-19 is an emerging, rapidly evolving situation. It is pronounced “pipes-ah”. Thanks to its efficient implementation, features and user-friendly command line interface, pydca is a modular and easy-to-use tool that can be used by researchers with a wide range of backgrounds. visualization of contact maps or true positive rates. Code is Open Source under AGPLv3 license Data is available under CC-BY-SA 4.0 license. plmDCA takes as input a Multiple Sequence Alignment and returns scores for pairwise (direct) interactions among the columns.

Supplementary data are available at Bioinformatics online. This site needs JavaScript to work properly. 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. Given multiple sequence alignment (MSA) files in FASTA format, pydca computes the coevolutionary scores of pairs of sites in the alignment. © The Author(s) 2019.

To obtain DCA scores from direct-information (DI) we replace the subcommand This article is also available for rental through DeepDyve. In addition, when an optional file containing a reference sequence is supplied, scores corresponding to pairs of sites of this reference sequence are computed by mapping the reference sequence to the MSA.

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.
