Description |
S10
|
Data processing |
Sequencing reads were mapped to GRCm38/mm10 reference genome using the Subread aligner in the Rsubread package. Only uniquely mapped reads were retained. Gene-wise read counts were obtained using the featureCounts program included in the Rsubread package. Only genes that achieved a CPM (counts per million) value greater than 0.5 in at least two samples and had known symbols were included in the downstream analysis. Predicted genes (gene names starting with “Gm”), ribosomal genes and genes on chromosomes X and Y were removed from analysis. Counts were converted to log2-CPM, quantile-normalized, and precision-weighted with the voom function in the limma package. Log2-CPM values were then converted to log2-FPKM (Fragments Per Kilobases per Million) values. A linear model was fitted to each gene to estimate expression levels of genes, which were then used to compute log2 fold changes of gene expression. GSEA was used to discover enriched Hallmark pathways included in the MSigDB database. Assembly: mm10 Supplementary files format and content: tab-delimited text files include normalized log2-FPKM values for each library. The supplementary file, Supp_Raw_Counts_bulkRNA.txt, includes raw read counts for genes in each sample (sample 4 and its tech replicate were merged).
