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. The other two command are associated with 2020 Nov 16;15(11):e0242072. RNA. PyPSA stands for “Python for Power System Analysis”. Bioinformatics. performance of pydca by contact map visualization. About pydca. Example: In addition to contact map we can evaluate the performance of pydca by plotting The command pydca is used for tasks such as trimming alignment data before DCA computation, and The software provides command line utilities or it can be used as a library.

Given multiple sequence alignment (MSA) files in FASTA format, pydca computes the coevolutionary scores of pairs of sites in the alignment. Physical Review E, 87(1), 012707, doi:10.1103/PhysRevE.87.012707, Something wrong with this page? Direct coupling analysis (DCA) is a statistical modeling framework designed to uncover relevant molecular evolutionary relationships from biological sequences. Search for other works by this author on: John von Neumann Institute for Computing, Jülich Supercomputer Centre, Forschungszentrum Jülich. The command compute_fn computes DCA scores obtained from the Frobenius norm of the couplings. 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. Here, we present pydca, a standalone Python-based software package for the DCA of protein- and RNA-homologous families. eCollection 2020. compute_fn by compute_di.
