I'm performing a WES analysis from Illumina. The specific kit used was Illumina DNA Prep with Enrichment (formerly known as Nextera Flex for Enrichment). I need both the target and the bait regions for the analysis, but the website provides only an "Illumina Exome Panel v1.2 (CEX) BED File" in BED format. Does it contain the bait or the target regions? I guess that file refers to the bait regions, whilst the target regions should be generated by adding all exon start/stop sites (maybe a flanking sequence too?) to a different BED file. Am I right?
