Predicting Glycan Composition from Experimental Mass Using GlycoMod

GlycoMod (http://www.expasy.org/tools/glycomod/)(1) is a computational tool that finds all possible compositions of a glycan structure from its experimentally determined mass. It may be used to calculate the possible compositions of free or derivatized glycan structures, or compositions of glycans attached to glycoproteins and glycopeptides.
