The FANTOM5 Consortium publishes an atlas of transcriptional activity covering 975 human and 399 mouse samples, including primary cells, tissues and cancer cell lines (FANTOM Consortium, 2014). Better still, the data were generated using single-molecule sequencing, avoiding the biases introduced by other approaches. As ever it was great fun to be involved in this unique international collaboration. All data are freely available from the FANTOM5 site.
