Files

Steps to reproduce

Command line preprocessing unzip all the sequencing files gunzip *.fastq.gz concatenate all files from the 4 lanes for each index. e.g. cat *69* > ../IND69.fastq Copy both Brett’s python script and Ashley’s sbatch script to current folder run Brett’s script to split samples within an index python fastqconvert_ApaI.py IND69.fastq S14-1.txt S14-2.txt S14-3.txt S14-4.txt ind69umapped python fastqconvert_ApaI.py IND70.fastq S14-5.txt S14-6.txt S14-7.txt S14-8.txt ind70unmapped python fastqconvert_ApaI.py IND71.fastq S14-9.txt S14-10.txt S14-11.txt S14-12.txt ind71unmapped python fastqconvert_ApaI.py IND72.fastq S14-13.txt S14-14.txt S14-15.txt S14-16.txt ind72unmapped grep samples with ApaI site and AscI site Sort and count unique barcodes sbatch grepANDsort.sh Download with Cyberduck and proceed to python SCRIPT grepANDsort.sh #!/usr/bin/env bash #Run command on HTCF: sbatch /home/arwolf/scripts/16S_processing.sbatch #Author: awolf@wustl.edu #SBATCH --mem=16000 for i in $(ls S*.txt); do grep -o GGCCCG.*.GGCGCGCC $i > "$i"grepped sort "$i"grepped | uniq -c > "$i"sorted.txt done #BINNAME= $(echo $i | cut -d '.' -f 1) ## consider updating this script to account for BC length at this stage—something like: ## grep -o GGCCCG………GGCGCGCC $i > "$i"grepped ## note necessary because the preprocessing python script checks for correct length, only advantage is that it would be faster at this stage, result in a smaller output file, and remove a slower check step later in the pipeline.
