CapSeq Read Density (tss_CapSeq) Track Description
 

Description

These tracks show the normalized density of CapSeq reads for Drosophila adult ovaries (genotype w1118.tm3). The CapSeq datasets were obtained from the NCBI Sequence Read Archive database under the accession number SRP103849.

Methods

Each dataset was mapped to the D. melanogaster release 6 assembly using bwa with default parameters. Only the alignments with mapping quality of 5 or above are kept. 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 = 1.05, T = 1*10^6
