xiNET: cross-link network maps with residue resolution.
Bottom Line: xiNET is a visualization tool for exploring cross-linking/mass spectrometry results.The interactive maps of the cross-link network that it generates are a type of node-link diagram.In these maps xiNET displays: (1) residue resolution positional information including linkage sites and linked peptides; (2) all types of cross-linking reaction product; (3) ambiguous results; and, (4) additional sequence information such as domains. xiNET runs in a browser and exports vector graphics which can be edited in common drawing packages to create publication quality figures. xiNET is open source, released under the Apache version 2 license.

Mentions: Fig. 2 provides an overview of the xiNET workflow. The input data sets for a cross-link map are: cross-link data; protein sequence data; and, optionally, annotation data. Sequence data can be omitted if UniProtKB (21) accession numbers are used as the protein identifiers, in this case protein sequences will be retrieved automatically using a web-service provided by UniProt1. If UniProtKB accession numbers are used then annotation data will also be retrieved from this web-service and from the SuperFamily (22) Distributed Annotation System (23) server2. Once data has been loaded into xiNET the CLMS network can be interactively explored and vector graphics can be exported for use in figures.
