Mehari B Zerihun, Fabrizio Pucci, Emanuel K Peter, Alexander Schug, pydca v1.0: a comprehensive software for direct coupling analysis of RNA and protein sequences, Bioinformatics, Volume 36, Issue 7, 1 April 2020, Pages 2264–2265, https://doi.org/10.1093/bioinformatics/btz892. 2020 Jul;26(7):794-802. doi: 10.1261/rna.073809.119. Department of Physics, Karlsruhe Institute of Technology. 2019 May 1;35(9):1582-1584. doi: 10.1093/bioinformatics/bty862. Results: Here, we present pydca, a standalone Python-based software package for the DCA of protein- and RNA-homologous families. RocaSec: a standalone GUI-based package for robust co-evolutionary analysis of proteins. 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. Get the latest public health information from CDC: https://www.coronavirus.gov. plmDCA takes as input a Multiple Sequence Alignment and returns scores for pairwise (direct) interactions among the columns. 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. Results: doi: 10.1371/journal.pone.0242072. Libraries.io helps you find new open source packages, modules and frameworks and keep track of ones you depend upon. Namely pydca, plmdca, and mfdca. Although DCA has been successfully used in several applications, mapping and visualizing of evolutionary couplings and direct information to a particular set of molecules requires multiple steps and could be prone to errors. 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 framework enables generation of sequence alignments, calculation and evaluation of evolutionary couplings (ECs), and de novo prediction of structure and mutation effects. PNAS December 6, 2011 108 (49) E1293-E1301, doi:10.1073/pnas.1111471108, Ekeberg, M., Lövkvist, C., Lan, Y., Weigt, M., & Aurell, E. (2013). 2020 Nov 16;15(11):e0242072. 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. It is pronounced “pipes-ah”. The command compute_fn computes DCA scores obtained from the Frobenius norm of the couplings. To whom correspondence should be addressed. When pydca is installed, it provides three main command.
