Dear all scientists,

I am dealing with RRBS data. I used VIM to read big data. Data are Methylation level (%) of both CpG sites and other couple nucleotide sites. I only want to get CpG sites not others. Anyone know how to deal with, could you be nice share me?

---Data information:

1) mice mm10

2) yellow signs are CpG sites, and I need them - I want to exclude all of other.
