Abstract excerpt
Sample pooling enabled by dedicated indexes is a common strategy for cost-effective and robust high-throughput sequencing. Index misassignment leading to mutual contamination between pooled samples has however been described as a general problem of the latest Illumina sequencing instruments utilizing exclusion amplification. Using real-life data from multiple tumour sequencing projects, we demonstrate that index...
