FIG 6 .
Preference for integration near genomic features. Enrichment for integration near genomic features was calculated with HOMER (40). Fold enrichment was calculated by comparing ALV integrations to a randomly generated integration data set. Promoters are defined as the region from −1 kb to +100 bp from transcription start sites, while transcription termination sites (TTS) are defined as the region from −100 bp to +1 kb flanking the transcription termination site.
