i have a data produce from nextseq 500 and i want to find the adapters which used in my data, how do i find that adapter in https://support.illumina.com/downloads/illumina-adapter-sequences-document-1000000002694.html
Normally they are Illumina TruSeq adapters.
If you don't know it, use fastp to detect the adapters automatically.
See https://github.com/OpenGene/fastp#adapters for details.
Remind to enable
--detect_adapter_for_pe option if your nextseq 500 data is paired-end.
