GlycoGlyph: A glycan visualizing, drawing and naming application.

MOTIVATION: Glycan structures are commonly represented using symbols or linear nomenclature such as that from the Consortium for Functional Glycomics (CFG) (also known as modified IUPAC condensed nomenclature). No current tool allows for writing the name in such format using a graphical user interface (GUI); thus, names are prone to errors or non-standardized representations. RESULTS: Here we present GlycoGlyph, a web application built using JavaScript, which is capable of drawing glycan structures using a GUI and providing the linear nomenclature as an output or using it as an input in a dynamic manner. GlycoGlyph also allows users to save the structures as an SVG vector graphic, and allows users to export the structure as condensed GlycoCT. AVAILABILITY: The application can be used at: https://glycotoolkit.com/Tools/GlycoGlyph/. The application is tested to work in modern web browsers such as Firefox or Chrome. SUPPLEMENTARY INFORMATION: Code, and instructions along with tutorials are available at https://github.com/akulmehta/GlycoGlyphPublic/.
