Data in DNase_seq_norm_iter0_hub was generated by Illumina Hi-Seq (X)
* Raw reads were mapped with bowtie (after stripping custom barcodes)
* Mappings were filtered for ENCODE blacklisted regions
* Mappings were filtered for PCR artifacts using a custom python script
* Mappings were corrected for GC bias as in Benjamini and Speed 2012 (doi: 10.1093/nar/gks001) and 
implemented in deepTools (Ramirez et al. 2014; doi: 10.1093/nar/gku365)
* Mappings were normalized by RPKM as implemented in deepTools (Ramirez et al. 2014; doi: 10.1093/nar/gku365)
