Here are now the new WIG files split into plus & minus strand. Up to alignment it is as described in "Extended Experimental Procedures". Afterwards the BAM files are merged (see 2) with samtools. The strandedness is converted to "forward-forward". All aligned reads are piled up to bedGraphs with "genomeCoverageBed" from BEDTools and split into +/- strand. The bedGraphs are converted to 1-based variable wiggle files. neuron.merge.plus.wig: 14336733 reads neuron.merge.minus.wig: 14379053 reads nb.merge.plus.wig: 67519599 reads nb.merge.minus.wig: 70186187 reads For the merged files following samples were used: GSM949245 wild type neuroblast 1 GSM949246 wild type neuroblast 2 (tech. Repl. 1) GSM949247 wild type neuroblast 2 (tech. Repl. 2) GSM949248 wild type neuroblast 3 (tech. Repl. 1) GSM949249 wild type neuroblast 3 (tech. Repl. 2) GSM949250 wild type neuron 1 (tech. Repl. 1) GSM949251 wild type neuron 1 (tech. Repl. 2) GSM949252 wild type neuron 2 Dr. Christian Berger Institute of Genetics University of Mainz
