I am a beginner....trying to use Trimmomatic to clean adaptors/index from my NextSeq500 data. And the Input FASTQ quality scores type is not compatible. Then I would like to convert formats using Groomer, but I do not know which FASTQ quality scores type I should specifiy: Illumina 1.8 or Illumina 1.7-1.3. Or I should not be using Goomer?
Thanks for your help!
