title: ATAC-seq of Gallus gallus: e9 Inferior Sternum, Biological Replicate 1
design: ATAC-seq libraries were generated as described in Buenrostro et al., (Curr Protoc Mol Biol, 2016) with 11 cycles of PCR.  45 ul of PCR product was cleaned using bead purification (0.4x to remove large fragments, followed by 1.4x to remove small fragments) with AmpureXP beads (Beckman Coulter).
