Twice or half the usual number of tiles for a fixed number of genomic bases – Therefore recommend an overall on-target sequencing coverage depth of at leastĢ00x to 300x with a read length of 100bp to justify reducing the average targetįor hybrid capture, if your targets are not tiled with uniform density –įor example, if your target panel is designed with a subset of targets having In practice we see good results with an average of 200–300 reads per bin we Zero reads, the segmentation algorithm could produce less accurate results on May not be normally distributed, especially in the presence of many bins with Increasing the variance or “noise” in bin-level coverages.Īn excess of noisy bins can make visualization difficult, and since the noise However, the number of reads counted in each bin will be reduced by about half, Twice as many target bins, which might result in higher-resolution segmentation. Setting the average size of target bins to 100bp, for example, will yield about Produced by splitting larger exons will be no worse than average. Noisier copy number signal, this approach ensures the “noisiness” of the bins Since bins that contain fewer reads result in a Size default of 267 is chosen so that splitting larger exons will produce bins If you need higher resolution, you can select a smaller average size for yourĮxons in the human genome have an average size of about 200bp.
