30-mer mappable regions in the human hg19 genome

Knowing where reads can uniquely map in the genome is useful for nascent RNA assays, both in statistical calculations and to make predictions. The dataset was created using the bowtie 1 aligner. The genome was windows at 30 basepair genomic intervals and mapped back to the genome. If the read maps to more than one place, the read is thrown away. Therefore the regions captured in the dataset are regions that any read at least 30 basepairs long will map to uniquely. The shell script originally used to create this dataset has been lost.
