STAR (v2.5.1b) was used to build an index of the reference genome and to align the paired-end clean reads to the reference genome. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine..
