MachiBase: a Drosophila melanogaster 5'-end mRNA transcription database


This series contains transcription start site mapping from MachiBase. The data were generated with the oligo-capping technology.


The source data were downloaded from:


From Fruit Fly Apr. 2006 (R5/dm3) Assembly

Technical Notes

According to the readme file included in the tar archive from MachiBase, the 5'end tags were mapped to the Drosophila genome using BLAT as alignment tool allowing for up to three mismatches.
