Examples of SynCircos and SynBrowser outputs. (A) A representative Circos plot generated by SynCircos, which compared three species and their specific chromosomes (Human: chr1, chr3, chr5, chr6, chr8, chr12, chr15, chr19; Mouse: chr1, chr3, chr7, chr17, chr18; and Cow: chr3, chr9, chr10, chr14, chr17, chr22). The highlighted ribbons represent syntenic relationships between human chromosome 1 and the chromosomes of the other species. (B) A representative image generated by SynBrowser which shows the relationships between human chromosome 3 and the related mouse chromosomes. The coordinates of homologous blocks in each synteny block can be seen when a specific genomic region is selected (the khaki-colored box in the center of the image). The red triangle indicates the position of the user-queried gene. (C) A representative gene browser produced by SynBrowser which shows the genes of the reference species (human in this image) in synteny blocks. Details of the annotated genes are provided via links to the UCSC genome browser.
