ChIP assays were performed as previously described25 (link) with the modifications using AR antibody (ActiveMotif, Carlsbad, CA) or AR C-19 (Santa Cruz Biotechnology, Dallas, TX) as described in the Supplementary methods (SMethods). Data generated by Active Motif using the ChIP-exo method and their AR antibody (ActiveMotif, Carlsbad, CA)53 (link) were used to map AR and AR-V7 binding ChIP-seq and ChIP-exo (STable 1) were analysed as described in SMethods, using the bowtie2 (version 2.3, default parameters) alignment software54 (link) and peaks were called using macs2 (version 2.1; − q < 0.05, otherwise mentioned)55 (link).
