Fig. 2From: Copy number analysis by low coverage whole genome sequencing using ultra low-input DNA from formalin-fixed paraffin embedded tumor tissueCopy number profiles of MCC sample MCT4 with DNA input of (a) 100 ng, (b) 20 ng, and (c) 5 ng. Each point represents the normalized read count ratio of a 50 kb sized bin. Separate chromosomes from 1 to 22 as well as X and Y are shown and a log2 (copy number/2) equal to zero corresponds to a copy number of 2. Segments were removed from highly repetitive or problematic regions [8]Back to article page
