Description cell line expressing shRNA to Nfib
processed data file:,, gene_expression_cqnnorm_deseq.csv
Data processing Reads were aligned to the genome using TopHat
Exons were found from RefSeq genes, and exons with the same start and end locations were merged.
The number of reads overlapping each merged exon was found using bedtools multicov (-q30). This count was summed for exons all mapping to a particular gene.
Counts were normalized for length and GC bias using cqnnorm (Hansen et al. 2012). The sum of all reads within exons was used for the size factors. The length of all exons per gene was summed to get the length covariate, and the GC covariate was the average GC content within exons annotated per gene.
Differential expressiond was found using DESeq2
Genome_build: mm10
Supplementary_files_format_and_content: gives start and end of merged exons per gene (mm10)
Supplementary_files_format_and_content: gives the number of reads intersecting each of the exons given by the bed file above.
Supplementary_files_format_and_content: *deseq_results.csv gives the output from deseq2. Columns appended by '.5' (or '1') assess signficance of abs value of log2fold change being greater than 0.5 (or 1)
