- APA: alternative polyadenylation
- 3'aQTL: 3′UTR alternative polyadenylation quantitative trait loci
This pipeline describes the step-by-step methods for analyzing dynamics alternative polyadenylation events across population-scale samples and performing association analysis between common genetic variants and APA usages to obtain a map of genetic regulation of APA.
The scripts in this repository have been tested on 89 samples from Geuvadis RNA-seq Project and GTEx Project. For conditions to reuse of these scripts please refer to LICENSE file.
Details on how to prepare environment and use the script can be found on GitHub wiki pages for this repository.
This pipeline relies on Dapars2 for APA quantification, Matrix-eQTL for association mapping, and SuSieR for fine-mapping.
