These algorithms take as input epigenomic datasets, such as chromatin immunoprecipitation-sequencing (ChIP-seq) measurements of histone modifications or transcription factor binding. They partition the genome and assign a label to each segment such that positions with the same label exhibit similar patterns of input data. SAGA algorithms discover categories of activity such as promoters, enhancers, or parts of genes without prior knowledge of known genomic elements. In this sense, they generally act in an unsupervised fashion like clustering algorithms, but with the additional simultaneous function of segmenting the genome. Here, we review the common methodological framework that underlies these methods, review variants of and improvements upon this basic framework, and discuss the outlook for future work. This review is intended for those interested in applying SAGA methods and for computational researchers interested in improving upon them.<\/jats:p>","DOI":"10.1371\/journal.pcbi.1009423","type":"journal-article","created":{"date-parts":[[2021,10,14]],"date-time":"2021-10-14T17:42:09Z","timestamp":1634233329000},"page":"e1009423","update-policy":"https:\/\/doi.org\/10.1371\/journal.pcbi.corrections_policy","source":"Crossref","is-referenced-by-count":39,"title":["Segmentation and genome annotation algorithms for identifying chromatin state and other genomic patterns"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2502-0262","authenticated-orcid":true,"given":"Maxwell W.","family":"Libbrecht","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1009-6379","authenticated-orcid":true,"given":"Rachel C.
