Length of the shortest paths from all nine periodic genes in the SCC (first row) to periodic genes in connected via at least one non periodic gene (first column).

For example the length of the shortest path from REB1 to WSC2 (first line) is 4. The number in brackets indicates the length of the minimal shortest paths.以从REB1到WSC2的最短路径（第一行示例）的长度为4为例。括号内的数字表示该起点到终点的最短路径的条数。
