Computational Methods

Transcript abundances were quantified using kallisto (Bray et al. 2016) and genome build GRCm38 release 98 (jul2019.archive.ensembl.org). Estimated counts for all transcripts per gene were summed to give a gene-level abundance estimation (Soneson et al. 2015).
Summed estimated counts were rounded to the nearest integer in order to run DESeq2 (Love et al. 2014) using a negative binomial LRT test with model (counts ~ time_point). This model tests in an anova-like way whether one timepoint differs from any other timepoint across the series.

Visualization Features

Gene panel plots can be displayed using normalized counts or rlog values from DESeq2 or transcripts per million from kallisto. The light grey dot represents the mean expression value for that gene at each timepoint and the dark grey dots represent the value for each replicate. The vertical line at each timepoint depicts the range of the data and a line has been drawn to connect the mean at each timepoint to show the expression profile.

The heatmap displays z-scores (computed using DESeq2 normalized counts) for the selected gene list using a red-blue color scale.
