Methylation Haplotype Block Plot

purpose

plot MHB heatmap block

Method

  • Bam2haploinfo from GWBS dataset
  • Merge All the haploinfo files
cd /home/shg047/oasis/monod/haplo/
cat /home/shg047/oasis/monod/haplo/n37/*hapInfo.txt >> hapinfo.txt
cat /home/shg047/oasis/monod/haplo/wbc/*hapInfo.txt >> hapinfo.txt

cat /home/shg047/oasis/monod/haplo/salk/*hapInfo.txt >> hapinfo.txt
  • Haploinfo to R-square matrix by Genomic Region
