This is a sub-sampled version (10X) of ChineseTrio HG007(mother) fastq files published by NIST's Genome in a Bottle project. We created them for practicing variant-call processes. These files are 10X fastq files. Though 30X fastq files are preferable for WGS analysis, we prepared 10X fastq files for reducing the burden of handling the large files.
