Figure 2From: Digital gene expression approach over multiple RNA-Seq data sets to detect neoblast transcriptional changes in Schmidtea mediterranea Venn stave showing the proportions of the distinct tags mapped over the different reference data sets. Integrating data for Venn diagrams for sets larger than four or five can be a challenging task, so that, a linear projection of such a diagram is provided in the stave—showing the 20 topmost scoring comparisons from 752 different subsets, accounting for 62.26% (18,710 out of 30,053) of total mappings—for ten reference sequence sets: eight transcriptomes, the S. mediterranea ESTs from NCBI dbESTs [39-42], and the latest genome draft AUVC01 [43,44]. Color gradient scale is provided on the bottom bar and it is proportional to the number of unique tags mapped over each sequence subset. X-axis ticks present the number of tags and their relative percent; the numbers on the right Y-axis correspond to the total number of tags mapped into a given sequence sets comparison. It is easy to spot that 15% of the unique reads are mapping onto all the sequence sets.Back to article page
