+
+The output is a tabular file listing the 1) compared genomes, 2) the rerrangemets, 3) the affected breakpoints.
+
+Rearrangements are listed as follows:
+
+- I(X): the genes listed in X are inverted
+- T(X ,Y ,): The order of the gene sets X and Y is transposed
+- iT(X, Y, ): Same as transposition, but one gene of the sets is also inverted
+- TDRL(X, Y): A tandem duplication random loss where the genes in X are kept in the 1st copy and the genes in Y an the last

+**What it does**
+
+Usage
+.....
+
+Compute a distance matrix for gene orders of unichromosomal genomes with equal duplication free gene content,
+e.g. mitochondrial gene orders. Several distance measures are available.
+
+- CREx distance (Bernt et al 2007) all other distance measures have been implemented
+  in this software package. 
+- Inversion distance (Bergeron, Heber & Jens Stoye 2002)
+- Number of Breakpoints (e.g. Sankoff, Blanchette 1997)
+- Common Intervals (Bergeron, A., Chauve, C., de Montgolfier, F., and Raffinot, M., 2008) 
+- Conserved Intervals (Bergeron, A., Blanchette, M., Chateau, A., and Chauve, C., 2004)
+
+For the latter a distance is computed by subtracting the number from the maximum possible for the number of genes.
+
+**Input**
+
+@INPUT_FORMAT@
+
+**Output**

+A tabular file showing the distance matrix.
