An example of the coordinate transformation results. (A) The ChIP-seq results from D. simulans. The coordinates have been converted into D. melanogaster using RECOT. The upper histogram indicates the number of reads associated with the position. The gray horizontal lines are short reads. The colored positions indicate differences from D. melanogaster genome. The black narrow bars indicate deletions. (B) The D. simulans gene regions with 500-bp upstream and downstream sequences. The sequence was mapped onto the D. melanogaster genome using GMAP. The result shows us that the non-coding region contains mutations and short deletions. (C) The ChIP-seq results from D. melanogaster (ERR020066).
