Read 1 sequences with adapter contamination will be trimmed a further 2 bp from their 3' end, and Read 2 sequences will be trimmed by 2 bp from their 5' end to remove potential methylation-biased bases from the end-repair reaction File was specified to be a non-directional MspI-digested RRBS sample. Sequences starting with either 'CAA' or 'CGA' will have the first 2 bp trimmed off to remove potential methylation-biased bases from the end-repair reaction Running FastQC on the data once trimming has completed Running FastQC with the following extra arguments: --outdir /gscratch/scrubbed/strigg/analyses/20200306/FASTQC Output file will be GZIP compressed This is cutadapt 2.4 with Python 3.7.3 Command line parameters: -f fastq -e 0.1 -O 1 -a AGATCGGAAGAGC /gscratch/scrubbed/strigg/analyses/20200306/Meth14_R2_001.fastq.gz_qual_trimmed.fastq WARNING: Option --format is deprecated and ignored because the input file format is always auto-detected Processing reads on 1 core in single-end mode ...
