Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: This study proposes a novel copy number variation CNV detection method, CNV_shape, based on variations in the shape of the read coverage data which are obtained from millions of short reads aligned to a reference sequence. The proposed method carries out two transforms, mean shift transform and mean slope transform, to extract the shape of a CNV more precisely from real human data, which are vulnerable to experimental and biological noises. The mean shift transform is a procedure for gaining a preliminary estimation of the CNVs by statistically evaluating moving averages of given read coverage data. The mean slope transform extracts candidate CNVs by filtering out non-stationary sub-regions from each of the primary CNVs pre-estimated in the mean shift procedure. Each of the candidate CNVs is merged with neighbours depending on the merging score to be finally identified as a putative CNV, where the merging score is estimated by the ratio of the positions with non-zero values of the mean shift transform to the total length of the region including two neighbouring candidate CNVs and the interval beten them. The proposed CNV detection method was validated experimentally with simulated data and real human data. The simulated data with coverage in the range of 1× to 10× re generated for various sampling sizes and p-values. Five individual human genomes re used as real human data. The results show that relatively small CNVs >1 kbp can be detected from low coverage > 1.7× data. The results also reveal that, in contrast to conventional methods, performance improvement from 8.18 to 87.90% was achieved in CNV_shape. The outcomes suggest that the proposed method is very effective in reducing noises inherent in real data as ll as in detecting CNVs of various sizes and types.
