Zhang14, Nucleosome organisation at promoters during genome activation


The chromatin organisation around promotrs is investigated using ChIP-seq and MNase-seq in two developmental stages (256-cell and dome) that are characterised by the shift between mathernal and zigotic mRNA usage.

Technical Notes

Raw data was downloaded from NCBI SRA database (ID SRA055273) and mapped to Zv9/danRer7 genome using Bowtie aligner. The resulting SAM files were converted to BED using SAMtools and BEDtools. Final conversion to SGA files was done using ChIP-Seq.
