Web1 Jan 2024 · Pathway and gene set overdispersion analysis (Pagoda2) (Version 0.1.1) [19] is a computational framework that aims to detect cell heterogeneity from scRNA-seq … Web18 Jan 2024 · Gene overdispersion varies as a function of abundance An alternative strategy for parameterizing θ leverages a well-characterized strategy for modeling counts in bulk RNA-seq data, where per-gene dispersion estimates have repeatedly been found to vary as a function of expression abundance [ 33, 34, 36, 37, 39 – 41 ].
WebThe methods they use within species are often phenetic (i.e. based on genetic distances), such as AMOVA (Meirmans, 2012) or structure plots (Ramasamy et al., 2014), rather than phylogenetic (based on gene trees). Since spatial phylogenetics does not make this distinction between within-species versus between-species analyses, a unified set of … Web18 Dec 2024 · Notice how while calculating the running sum for genes that do not lie in the gene set we do not add their ranks but just add 1 to the running sum. This gives us the intuition that we want to give weightage to genes lying in the gene set and we are more concerned with that. Running sum for genes in gene set¶
WebThe gene-set analysis methods are applicable to transcriptomic data from both microarrays and RNA-seq. One caveat, however, is that the results need to take gene length into account. RNA-seq tends to produce higher …
