Data for the analysis of human trachea were obtained from GEO accessions GSE143705 (bulk RNA-seq) and GSE143706 (scRNA-seq). r - FindMarkers from Seurat returns p values as 0 for highly I used ggplot to plot the graph, but my graph is blank at the center across Log2Fc=0. 6e), subject and mixed have the same area under the ROC curve (0.82) while the wilcox method has slightly smaller area (0.78). Four of the methods were applications of the FindMarkers function in the R package Seurat (Butler et al., 2018; Satija et al., 2015; Stuart et al., 2019) with different options for the type of test performed: for the method wilcox, cell counts were normalized, log-transformed and a Wilcoxon rank sum test was performed for each gene; for the method NB, cell counts were modeled using a negative binomial generalized linear model; for the method MAST, cell counts were modeled using a hurdle model based on the MAST software (Finak et al., 2015) and for the method DESeq2, cell counts were modeled using the DESeq2 software (Love et al., 2014). ## [121] tidyr_1.3.0 rmarkdown_2.21 Rtsne_0.16 . In order to contrast DS analysis with cells as units of analysis versus subjects as units of analysis, we analysed both simulated and experimental data. One such subtype, defined by expression of CD66, was further processed by sorting basal cells according to detection of CD66 and profiling by bulk RNA-seq. (a) t-SNE plot shows CD66+ (turquoise) and CD66- (salmon) basal cells from single-cell RNA-seq profiling of human trachea. Before you start. 6f), the results are similar to AT2 cells with subject having the highest areas under the ROC and PR curves (0.88 and 0.15, respectively), followed by mixed (0.86 and 0.05, respectively) and wilcox (0.83 and 0.01, respectively). ## [11] hcabm40k.SeuratData_3.0.0 bmcite.SeuratData_0.3.0 ## Platform: x86_64-pc-linux-gnu (64-bit) Seurat has four tests for differential expression which can be set with the test.use parameter: ROC test ("roc"), t-test ("t"), LRT test based on zero-inflated data ("bimod", default), LRT test based on tobit-censoring models ("tobit") The ROC test returns the 'classification power' for any individual marker (ranging from 0 . ## [91] tibble_3.2.1 bslib_0.4.2 stringi_1.7.12 FindMarkers from Seurat returns p values as 0 for highly - ECHEMI The analyses presented here have illustrated how different results could be obtained when data were analysed using different units of analysis. Was this translation helpful? This issue is most likely to arise with rare cell types, in which few or no cells are profiled for any subject.
