Description Usage Format Source References Examples

Description

Gene expression time series for 4028 genes involved in the life cycle of Drosophila melanogaster. The microarray data measured gene expression levels during all four major stages of morphogenesis: embryo, larva, pupa and adult (67 time points). Data published in Arbeitman et al. (2002) and used in Lebre et al. (2010)

Usage

1

Format

A matrix of 4028 row (genes) by 67 columns (timepoints) containing the gene expression time series.

Source

The data has been published in Arbeitman et al (2002).
