Concatenation
Splitting the rawdata into lanes is not really necessary for these experiments, so the above were concatenated to form:
rawcatdata/ ├── ULS1_INP_R1.fastq.gz ├── ULS1_INP_R2.fastq.gz ├── ULS1_IP_R1.fastq.gz ├── ULS1_IP_R2.fastq.gz ├── ULS1_T2_INP_R1.fastq.gz ├── ULS1_T2_INP_R2.fastq.gz ├── ULS1_T2_IP_R1.fastq.gz ├── ULS1_T2_IP_R2.fastq.gz ├── WT_T2_INP_R1.fastq.gz ├── WT_T2_INP_R2.fastq.gz ├── WT_T2_IP_R1.fastq.gz └── WT_T2_IP_R2.fastq.gz

Dataset quality analysis and filtering
Raw unfiltered data
Using FASTQC to view quality aspects inidvidually:
- ULS1_INP_R1
- ULS1_INP_R2
- ULS1_IP_R1
- ULS1_IP_R2
- ULS1_T2_INP_R1
- ULS1_T2_INP_R2
- ULS1_T2_IP_R1
- ULS1_T2_IP_R2
- WT_T2_INP_R1
- WT_T2_INP_R2
- WT_T2_IP_R1
- WT_T2_IP_R2
and then MultiQC to integrate the FASTQC files into one report
Adaptor-cutting and filtering procedure
The program cutadapt was applied first (this is advised) and then trimmomatic in the following manner
cutadapt -g ACACTCTTTCCCTACACGACGCTCTTCCGATCT...GATCGGAAGAGCGGTTCAGCAGGAATGCCGAG ${SAMP} -o ${OUTDIR}
RL="ILLUMINACLIP:${TS3PE2}:2:30:10 LEADING:5 TRAILING:5 SLIDINGWINDOW:4:15 MINLEN:49"
java -jar $TRIMMOJARFILE PE -threads $THRDS -phred33 $SAMP1 $SAMP2 $OUTR1 $OUTSING1 $OUTR2 $OUTSING2 $RL
The integrated MultiQC report is as follows:
The individual FastQC reports are as follows:
