ko数据库ID转换
Since the clusterProfiler is a very useful tools for GO and Kegg annotation.At present I want to use it to enrich for kegg result while only have the KO number ,So I want to convert the KO number to the pathway function,Is there have any function or methods in the software can convert it?any help will be appreciated
这个问题问说他想转KO到通路，首先这是一个常见的错误，很多人分不清K和ko，所以在我告诉他可以把K number转成ko pathway的时候，我先指出他的错误。
ko is actually pathway map. I think you are talking about K number mapping to ko pathway.

15 K00844 ko04930
16 K00844 ko04973
17 K00844 ko05230Yeah,sorry,It’s really the K number,Since I want to obtain the pathway according the K number,such like this ,did have any methods to achieve it ?

然后对方继续问，说想要通路的名字而不是ko号。于是我随手写了个ko2name的函数：
just write a ko2name function for this purpose.
