Exo-seq Tag Clusters (tss_exoseq_tagClusters) Track Description
 

Description

These tracks show the interquantile widths of the promoters for D. melanogaster based on the Exo-seq data collected at different Zeitgeber Times (ZT) and temperatures. The Exo-seq datasets were obtained from the NCBI Sequence Read Archive database under the accession number SRP045351.

Methods

Each dataset was mapped to the D. melanogaster release 6 assembly using bwa with default parameters. The alignment results were analyzed by CAGEr. The tag counts were normalized by the normalizeTagCount function in CAGEr with the following parameters:

method = "powerLaw", fitInRange = c(10, 1000), alpha = 1.16, T = 1*10^6

The promoter widths were determined by the cumulativeCTSSdistribution and quantilePositions functions in CAGEr using the following parameters:

clusters = "tagClusters", qLow = 0.1, qUp = 0.9

Display Conventions

The span of each feature corresponds to the promoter width. The thin box within each span corresponds to the interquantile width (qLow = 0.1 to qUp = 0.9) that captures 80% of the CAGE signal. The thicker box denotes the position within the promoter with the highest CAGE signal.
