CpG岛预测
CpG岛预测 reports potential CpG island regions using the method described by Gardiner-Garden and Frommer (1987). The calculation is performed using a 200 bp window moving across the sequence at 1 bp intervals. CpG岛预测 are defined as sequence ranges where the Obs/Exp value is greater than 0.6 and the GC content is greater than 50%. The expected number of CpG dimers in a window is calculated as the number of 'C's in the window multiplied by the number of 'G's in the window, divided by the window length. CpG岛预测 are often found in the 5' regions of vertebrate genes, therefore this program can be used to highlight potential genes in genomic sequences.
