Identification of putative transcription start points. A window slides across the nucleotide sequence of the coverage depth file and finds segments of coverage depth highly and statistically correlated with a vector of 100 integers modeling a simple shape of sharp increases in transcription (x = [0₅₀,1₅₀]). For each highly and statistically correlated segment, we select the center point to indicate a potential transcription start point.
