Motivation and Discovery

Data Introduction

1) Normal pregnancies (17 sample, paired-end)
2) Organ transplantation patients (7 samples, paired-end)
3) Pregnancies with trisomy 21 fetus (5 samples, paired-end) 
4) Healthy control plasma samples (32 samples, single-end)
5) Hepatocellular carcinoma (HCC) patient samples (29 samples, single-end)
6) Lymphoma case (4 sample, paired-end, multiple sequencing runs)

Data Storage

Data Re-analysis

Trim_galore

  • do the trim_galore and bismark one by one to avoid the OUTPUT error
cd /home/shg047/oasis/DennisLo2015/fastq_trim
ls *fq.gz # 127 trimed fastq file

Bismark Alignment

  • analysis the data with free glean quene
  • mulitple core=6 will use 128G memory.
  • the data is complicated since single-end and pair-end samples are mixed
cd /home/shg047/oasis/DennisLo2015/fastq
perl ../bismark.pbs.pl ../Sample_queue.txt
