WebOct 4, 2024 · DCA (direct-coupling analysis) methods shed some light on this, but they need many sequence homologs to yield accurate prediction. Inspired by the success of our deep-learning method for intraprotein contact prediction, we have developed RaptorX-ComplexContact, a web server for interprotein residue–residue contact prediction. WebThe DCA webservice is a public server to analyse protein multiple sequence alignments (MSA) and compute direct couplings among amino acid pairs within the MSA. In order to use the service, a user must register with the only purpose to have a way to organize the jobs submitted by each user. The user will have access to the workbench tab, were ...
