Data Browsing and Visualization. A Data Set Browsing. Different datasets generated from the original sequencing data can be browsed. Here five different dataset types are attached to one sequencing sample. B Nucleotide distribution plot. Barplot showing the distribution of nucleotides per sequencing cycle. C Quality plot. Histogram showing the Phred quality scores distribution per sequencing cycle. D Data. Aligned Data stored in SAM/BAM file format. E For visualization of the ChIP-seq data the Wig file can be exported to the UCSC Genome Browser . The screenshot shows a typical binding profile of the PcG protein Polyhomeotic (Ph) in the homeotic cluster BX-C.
