Data described here is associated with the Yang et al., 2017, PLOS Genetics. The data types in this directory tree are: GERP annotation data, bam and SNP data, and ReadMe text file. For sequencing, we extracted DNA from the 12 inbred lines (See SRA_metadata_acc_inbred12) and sheared the DNA on a Covaris (Woburn, Massachusetts) for library preparation. Libraries were prepared using an Illumina paired-end protocol with 180 bp fragments and sequenced using 100 bp paired-end reads on a HiSeq 2000. Raw sequencing data are available at NCBI SRA (PRJNA381642). Please refer Yang et al., 2017 for more details about read mapping, SNP calling and GERP annotation.
