GlyCombo is an open source software for combinatorial glycan composition determination to identify glycans in MS acquisitions of glycan-containing samples in text or mzML formats. This application enables rapid extraction of precursor m/z values from mzML files, a vendor-neutral format that ensures cross-platform compatibility.
Features
- Open-source Windows application created in C#.
- Unlimited monosaccharide and modification options including Hex, HexNAc, dHex, Neu5Ac, Neu5Gc, HexN, HexA, dHexNAc, Pent, KDN, Phosphate, Sulfate, and Custom monosaccharides.
- Support for native, peracetylated, and permethylated glycan samples.
- Support for all commonly observed adducts by MS, including custom adducts and the ability to search for multiple adducts in the same search.
- Support for free, reduced, and tagged glycans.
- Automatic polarity extraction for mzML input files.
Input and Output Options
| Output Options | mzML File Input | Text List of Masses |
