CYTO-95-769-s012.docx (28K) GUID:?CDA0F023-FBB0-4873-83D9-B0FF90712C14 Abstract Mass cytometry by time\of\trip (CyTOF) is a very important technology for high\dimensional analysis in the single cell level. Recognition of different cell populations can be an essential task through the data evaluation. Many clustering equipment can perform this, which is vital to recognize fresh cell populations in explorative tests. However, counting on clustering can be laborious because it frequently requires manual annotation, which significantly limits the reproducibility of identifying cell\populations across different samples. The latter is particularly important in studies comparing different conditions, for example in cohort studies. Learning cell populations from an annotated set of cells solves these problems. However, currently available methods for automatic Mecarbinate cell population identification are either complex, dependent on prior biological knowledge about the populations during the learning process, or can only identify canonical cell populations. We propose to use a linear discriminant analysis (LDA) classifier to automatically identify cell populations in CyTOF data. LDA outperforms two state\of\the\art algorithms on four benchmark datasets. Compared to more complex classifiers, LDA has substantial advantages with respect to the interpretable performance, reproducibility, and scalability to larger datasets with deeper annotations. We apply LDA to a dataset of ~3.5 million cells representing 57 cell populations in Mecarbinate the Human Mucosal Immune System. LDA has high performance on abundant cell populations as well as the majority of rare cell populations, and provides accurate estimates of cell population frequencies. Further incorporating a rejection option, based on the estimated posterior probabilities, allows LDA to identify previously unknown (new) cell populations that were not encountered during training. Altogether, reproducible prediction of cell population compositions using LDA opens up possibilities to analyze large cohort studies based on CyTOF data. ? 2019 The Authors. published by Wiley Periodicals, Inc. with respect to International Culture for Advancement of Cytometry. as the solitary dimension event in CyTOF data, may be Mecarbinate the true amount of markers for the CyTOF -panel.
