Abstract:Chromatography is a basic process in the current proteomics workflow,and the retention time alignment of the chromatogram is one of the important steps to effectively improve the identification and quantification accuracy.After years of development,a series of algorithms for retention time alignment have been developed.This review summarizes the advances of chromatographic retention time alignment algorithms and tools for proteomics analysis from the perspective of proteomics users,and discusses the development and future application directions.
