The input fastq files must contain absolute path. For example, if the input file read1.fq is under current directory /home/ubunto, the input fastq should be /home/ubunto/read1.fq instead of read1.fq. If the input file read1.fq is under parent directory /home, the input fastq should be /home/read1.fq instead of ../read1.fq. Otherwise, the script will not work. | |||

PPR PROGRAM
Guaranteeing high quality next-generation sequencing (NGS) data in a rapidly changing environment is an ongoing challenge. The recent introduction of the Illumina NextSeq500 and the depreciation of specific metrics from Illumina's Sequencing Analysis Viewer (SAV) have made it more difficult to directly determine the baseline error rate of sequencing runs. We have created an open-source tool to construct the Percent Perfect Reads (PPR) plot previously provided by the Illumina sequencers. The PPR program is compatible with HiSeq2000/2500, MiSeq, and NextSeq500 instruments, and provides an alternative to Illumina's Q scores for determining run quality.
The software is designed to be run in a UNIX/LINUX environment.
Dependencies:
Commands:
GENERIC:
cd [CODE DIRECTORY] perl ./NGS_missmatch_qc.pl [RUNTYPE] (ABSOLUTE_PATH/FASTQ FILES)
IMPORTANT NOTE:
The input fastq files must contain absolute path. For example, if the input file read1.fq is under current directory /home/ubunto, the input fastq should be /home/ubunto/read1.fq instead of read1.fq. If the input file read1.fq is under parent directory /home, the input fastq should be /home/read1.fq instead of ../read1.fq. Otherwise, the script will not work.

For paired end MiSeq sequencing:
perl ./NGS_missmatch_qc.pl miseq_paired_end read1.fq read2.fq
For single end MiSeq sequencing
