FLASHDeconvHelperStructs Struct Reference

Wrapper struct for all the structs needed by the FLASHDeconv Three structures are defined: PrecalculatedAveragine, TopPicItem, and LogMzPeak i) PrecalculatedAveragine - to match observed isotopic envelope against theoretical one, theoretical envelope from averagine model should be quickly calculated. To do so, precalculate averagines for different masses at the beginning of FLASHDeconv runs ii) TopPicItem - represent TopPic identification. Currently used for Qscore training. TopPic is the top-down proteomics identification tool (https://www.toppic.org/). iii) LogMzPeak - Log transformed peak from original peak. Contains information such as charge, isotope index, and uncharged mass. More...
