Capturing somatic mutations in single-cell probe-based assays (ie. 10X Flex) is a hard task, especially if you don't know *exactly* the mutations you want to capture, or if your target sequence is a mutational hotspot with many possible alternative alleles. Here's the way we pulled this off. Enjoy!
