2 cwpair2.py
3
4 Takes a list of called peaks on both strands and produces a list of matched pairs and a list
5 of unmatched orphans using a specified method for finding matched pairs. Methods for finding
6 matched pairs are mode, closest, largest or all, where the analysis is run for each method
7
8 Input: list of one or more gff format files
9
10 Output: files produced for each input/mode combination:
11 MP (matched_pair), D (details), O (orphans), P (frequency preview plot), F (frequency final plot),
12 C (statistics graph), statistics.tabular
