52,844 polyadenylation sites (PASs) were identified and used for genome-wide statistics in the Liu et al., 2017 publication (FBrf0237295). For downstream analysis, only the 46,314 sites with ≥ 2 "polyA site supporting" (PASS) reads were used for downstream analysis; PASS reads are defined in Hoque et al., 2014 (PMID: 24590784). These more stringent PAS calls are in the attached file, with PASS scores in column 4.
Coordinates in this file are relative to the Release 5 assembly (superceded by the Release 6 assembly at time of this personal communication).
