unable to find an inherited method for function "assays" for signature "standardGeneric"

[wangruohan111]

Hi, thank you for your method. I tried your sample data and it worked fine. When I used my own data, it successfully generated the count matrix, but next the program encountered a problem as below:

Error in (function (classes, fdef, mtable) :
unable to find an inherited method for function "assays" for signature "standardGeneric"?
Calls: epiAneufinder -> as.data.table -> assays ->
Execution halted

Could you please give any suggestions?

Thanks in advance.

Hi Rouhan,

This suggests that the count matrix isn't an assay as it should be. Could you provide the whole traceback?

I also have the same problem and I am having trouble tracing back the source of the error.

Hi Ruohan,

first of all I am sorry for the late response.
We can't be sure that this is same cause of this error, but we have seen it when the count matrix is generated, but is empty.
We have added an error message in our new package version that will be raised in this situation.
Can you please run with your data again and tell us if you get the same error again, in case you are still interested?

Best,
Katia
