# this file is to convert mult mapped reads to nm reads by simply marked it as NM reads. 
# its for the convience of inclusion ratio computation, if one read can be mapped to mult positions in the genome, then it will be marked as NM
# later, can be used to add information for dealing with this mult reads, for example, the coverage in the region
