Some questions about OTUs in each group

[zhangy-zy775]

Dear Ning:
In my analysis,my treat file has juet one OTU in each group.When I use icamp package to calculate icamp.big,R will feedback error:

Error in [.data.frame(weight, (sig.phy > sig.phy.cut | sig.phy2 > sig.phy2.cut)) :
dims [product 2]与对象长度[11]不匹配

But when I add OTU to each group and make sure the number of OTUs in each gruop greater or eaqul to 2,the program can calculate smoothly.

Why is this happening?

I am not sure what you mean by ‘treat file’.
In my code, “treat” is to specify the groups of samples rather than OTUs, like the example file ‘treat2col.txt’. I usually suggest each group has at least 6 samples.
