WebAdditionally, we can use regression to remove any unwanted sources of variation from the dataset, such as cell cycle, sequencing depth, percent mitocondria. This is achieved by doing a generalized linear regression using these parameters as covariates in the model. Then the residuals of the model are taken as the "regressed data". WebFor more than 100 years, the fruit fly Drosophila melanogaster has been one of the most studied model organisms. Here, we present a single-cell atlas of the adult fly, Tabula Drosophilae , that includes 580,000 nuclei from 15 individually dissected

NOTE: Alternatively, we could wait and perform the clustering without regression and see if we have clusters separated by cell cycle phase. If we do, then we could come back and perform the regression. scRNA-seq is maintained by hbctraining.
