  1. Column sG and dG are the source and destination group. Rearrangement scenario is calculated from the permutation of the source group to the destination group. For dG with a asterisk, the reversal event is calculated from the permutation of sG to permutation of dG in the negative strand. For example, if the permutation of dG is 1, 2, 3, then the permutation of dG in the negative strand is -3, -2, -1. Column revd indicates the reversal distance between sG and cG after eliminating other independent rearrangement events. Column rd indicates the distance of independent rearrangement events other than reversals. len is the length (in mbp) of reversal. Column IR lists which pair of inverted repeats (P, Q or R) flanks the reversal. The numeric code: 0 indicates the respective IR was found only in the source group, 1 indicates the IR was found only in the closest group, 2 indicates the IR was found in both groups
