MolEvolvR allows users to start with protein(s) of interest and perform the full analysis (1 3 & 4 below), only protein characterization (1 & 3 below), only homology searches (1 & 4 below), or start with external outputs from BLAST or Interproscan for further analysis, summarization, and visualization (2 3 & 4 below). MolEvolvR is interactive, queriable, and customizable.
