**What it does**

The ChIP-seq Mapper evaluates the enrichment of repetitive sequences in sequencing data from chromatin 
immunoprecipitation experiments, using repeats identified by RepeatExplorer as the reference. The tool 
performs BLASTN similarity search of the read sequences to the reference, 
and the reads producing hits that passed the user-specified similarity threshold are assigned to the 
repeat clusters. The assignment is made to the cluster that produced the best similarity hit, and every 
read is assigned to only a single cluster. Following read mapping, the numbers of reads from the 
INPUT and ChIP samples are evaluated, and ChIP/INPUT ratios of the normalized read counts are reported 
for individual clusters.
ChIP and INPUT reads should be of uniform lengths of at least 40 nt. The bit score threshold value should be
adjusted based on the length of the analyzed reads (the value equal to the read length is recommended for a start). 
This method was first used in (`Neumann et al. 2012`__) for
identification of repetitive sequences associated with centromeres:
