Before revision:  Tapestry combines ideas from compressed sensing and combinatorial group testing with a novel noise model for PCR . Unlike Boolean group testing algorithms, the input is a quantitative readout from each test , and the output is a list of viral loads for each sample  .
After revision:  Tapestry combines ideas from compressed sensing and combinatorial group testing with a novel noise model for RT-PCR used for generation of synthetic data . Unlike Boolean group testing algorithms, the input is a quantitative readout from each test , and the output is a list of viral loads for each sample .
