SUMMARISING RUN PARAMETERS ========================== Input filename: /gscratch/scrubbed/sr320/froger-raw/00_fastq/Meth13_R2_001.fastq.gz Trimming mode: paired-end Trim Galore version: 0.6.4_dev Cutadapt version: 2.4 Python version: could not detect Number of cores used for trimming: 8 Quality Phred score cutoff: 20 Quality encoding type selected: ASCII+33 Using Illumina adapter for trimming (count: 457885). Second best hit was Nextera (count: 0) Adapter sequence: 'AGATCGGAAGAGC' (Illumina TruSeq, Sanger iPCR; auto-detected) Maximum trimming error rate: 0.1 (default) Minimum required adapter overlap (stringency): 1 bp Minimum required sequence length for both reads before a sequence pair gets removed: 20 bp File was specified to be an MspI-digested RRBS sample. 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 Output file will be GZIP compressed This is cutadapt 2.4 with Python 3.7.6 Command line parameters: -j 8 -e 0.1 -O 1 -a AGATCGGAAGAGC /gscratch/scrubbed/strigg/analyses/20200316/Meth13_R2_001.fastq.gz_qual_trimmed.fastq Processing reads on 8 cores in single-end mode ...
