hi,
the hits are the matches of smallRNAs against the genome(have their coordinates like start and stop in a file example: 105, 1) . the clusters are grouping of these hits into one big cluster if only the other cluster is 200 basepairs away from the initial hit. as i have mentioned inthe previous post, the first three should be made into one cluster ie the cordinates of the first cluster would be 1 , 105.
