SraTailor is a simple GUI software for visualizing published ChIP-seq raw data (Video 1).

Main function of SraTailor is to convert SRAs into BigWig files.
  SRAs: High-throughput sequence raw data deposited in public databases.
  BigWig: Suitable format for graphically visualizing with genome browser.

Much simple usage is one of the most remarkable features of SraTailor. For example, SraTailor makes BigWig file only by entering an accession number of SRA of published ChIP-seq data. Resultant BigWig file allows you to view the protein occupancy at the genomic position of interest (Video 2). Setup of SraTailor is much easy and simple (Video 3).

As input, SraTailor also accepts your Fastq files, which are the raw sequence data produced by your own sequencing experiments (Video 5). SraTailor produces not only BigWig files but, optionally, also BAM and peak-call BED files. Also available is to process with command-line-like optional settings (Video 4).

SraTailor is a free software and runs on Mac, Windows, and Ubuntu!
