Program: UnSubPatt
Programming language: this implementation is coded using perl and distributed as PAR package
Plateform: tested on Linux(Ubuntu x86)
Commande line: ./UnSubPatt $param1 $param2 $param3
	$param1: file containing the frequent subgraphs
	$param2: minimum substitution threshold t (between 0 and 100, 0<= t < 100)
	$param3: substitution matrix (current release contains Blosum62, Blosum80 and PAM250)

Output: file cotaining the representative unsubstituted subgraphs (named: $param1.s)
Accepted format: lg format since it is the input/output format of gSpan (the state-of-the-art tool for frequent subgraph discovery)
