A comparison between the actual and predicted chromosome-wide locations of H3K4me2, H3K27me3 and H3K9me3. UCSC genome browser tracks of chromosome-wide predictions (pred, shown as probability) of H3K4me2, H3K27me3 and H3K9me3, compared with experimental data ChIP-SEQ data (exp, shown as tag count ), both in 25 kb sliding windows. Both a gene-poor chromosome, chromosome 4 (A), and a gene-rich one, chromosome 19 (B), are shown. Number of RefSeq genes in every sliding window is shown as a separate “Gene Density” track. In (C), details of each histone mark and their predictions are shown for a 400 kb genomic region on chromosome 19, along with all RefSeq genes within this region.
