CHROM染色体指数,X是编码为23和24Ÿ。
length Length of each chromosome in megabases.

Details
详情----------Details----------
This file is used for many plotting functions. The centromeric location is approximately estimated by taking mid-point between the last fish-mapped clone on the p-arm and the first fish-mapped clone on the q-arm using relevant UCSC freeze. For an alternative freeze, one needs to manually create a 3-column file of the format described above.
此文件用于许多绘图功能。估计约为中点P-臂和使用UCSC的有关冻结Q-臂的第一条鱼,映射克隆鱼之间的映射克隆着丝粒的位置。一种替代的冻结,需要手动创建一个文件上面描述的格式3列。
