# Locate the MethPipe Files

Several files MethPipe-associated files were already provided in the ALPS1 server and they can be found in the `/work3/NRPB1219` folder.

```bash
ls -lah /work3/NRPB1219/hg18_*
```

```

For reader who do not have an account on the ALPS server, you may download these files from Dropbox [HERE](https://www.dropbox.com/sh/fwt3cgski58ih3l/AADQ2Ajs6OkgBSXza14RR0Uba?dl=0) then use `gunzip` to unpack.

```bash
gunzip hg18_*.gz
```

And you may use `awk` commands to transform `.meth.corrected` files into bedGraph format, and `.hmr` and `.pmd` files to BED format.

```bash
awk -F $'\t' 'BEGIN { OFS=FS } { print $1,$2,$2+1,$5 }' hg18_h1_bsseq_methpipe.meth.corrected > hg18_h1_meth.bedGraph
awk -F $'\t' 'BEGIN { OFS=FS } { print $1,$2,$2+1,$5 }' hg18_imr90_bsseq_methpipe.meth.corrected > hg18_imr90_meth.bedGraph
awk -F $'\t' 'BEGIN { OFS=FS } { density = $5/($3-$2)*1000; print $1,$2,$3,$4,sprintf("%d",density),$6 }' hg18_h1_bsseq_methpipe.hmr > hg18_h1_hmr.bed
awk -F $'\t' 'BEGIN { OFS=FS } { density = $5/($3-$2)*1000; print $1,$2,$3,$4,sprintf("%d",density),$6 }' hg18_imr90_bsseq_methpipe.hmr > hg18_imr90_hmr.bed
awk -F $'\t' 'BEGIN { OFS=FS } { density = $5/($3-$2)*100000; print $1,$2,$3,$4,sprintf("%d",density),$6 }' hg18_h1_bsseq_methpipe.pmd > hg18_h1_pmd.bed
awk -F $'\t' 'BEGIN { OFS=FS } { density = $5/($3-$2)*100000; print $1,$2,$3,$4,sprintf("%d",density),$6 }' hg18_imr90_bsseq_methpipe.pmd > hg18_imr90_pmd.bed
