Clustering mapped reads

When working with reads that represent transcriptional starting sites (TSSs), such as CAGE data, reads do not always map at the same position. This is mainly because RNA Polymerase II initiates transcription from different positions. One way to study the … Continue reading

Is there any nucleotide bias with the -40 region of RefSeqs? Taking all hg19 RefSeqs that mapped to assembled chromosomes (36,004) and extracting the nucleotide sequences 40 bp upstream of the RefSeq gene model, I generated a sequence logo. No … Continue reading
