In order to reduce the gene expression matrix to its most important features, Space Ranger uses Principal Components Analysis (PCA) to change the dimensionality of the dataset from (spots x genes) to (spots x M) where M is 10. The pipeline uses a python implementation of IRLBA algorithm, ...
Run gseapy inside python console: Prepare expression.txt, gene_sets.gmt and test.cls required by GSEA, you could do this import gseapy # run GSEA. gseapy.gsea(data='expression.txt', gene_sets='gene_sets.gmt', cls='test.cls', outdir='test') # run prerank gseapy.prerank(rnk='...

ClusterMap integrates spatial and gene expression analyses Spatial clustering analysis in mouse brain Fig. 2: ClusterMap generates cell-type and tissue-region maps in mouse primary cortex (V1). In the mouse V1 cortex dataset, ClusterMap identified cell types22that matched both expression signature an...
Differential co-expression analysis: Genes that are differentially co-expressed between different sample groups are more likely to be regulators(调控因子), and are therefore likely to explain differences between phenotypes Differential co-expression analysis between sample groups ...
In order to reduce the gene expression matrix to its most important features, Cell Ranger uses Principal Components Analysis (PCA) to change the dimensionality of the dataset from (cells x genes) to (cells x M) where M is a user-selectable number of principal components (via num_principal_...
gene expression data and is meant to give a general method for setting up an environment and running alignment tools. Be aware that is not meant to be used for all types of analyses and data-types, and the alignment tools are not for every analysis. Additionally, this tutorial is focused ...
Compared to RNA-sequencing transcript differential analysis, gene-level differential expression analysis is more robust and experimentally actionable. However, the use of gene counts for statistical analysis can mask transcript-level dynamics. We demonst
We used the quality surrogate variable analysis (qSVA) framework to estimate and remove RNA quality confounding in differential expression analysis. First reads were mapped to the GRCh38 human reference genome with HISAT2 version 2.2.1 [46] using –rna-strandness RF option (Supplementary Fig. 2...
