Table 1. Characteristics of the reads from pectoral libraries obtained from 2 breeds of chicken.

Samples ID	Raw reads	Clean reads	Mapped reads	Mapped Pair Reads	Mapped Unique Reads1	Mapped Multi reads	Mapping ratio2	Uniquely mapping ratio3
A4	70,151,126	70,137,370	64,426,854	60,942,128	61,217,966	3,208,888	91.9%	87.3%

¹Mapped Unique reads = reads that matched only one position in the genome.

²Mapping ratio = mapped reads/clean reads.

³Unique mapping ratio = mapped unique reads/clean reads.
