I'm using BSprepare function in R package MethylPipe to perform binomial test. The paper says "The resulting multiple-testing corrected p-values are stored on the disk in the Tabix compressed and indexed file, and are available in methylPipe through the BSdata class. "

I wonder how to get the original pvalue of binomial test (not multiple-testing corrected).

Thank you so much.

Hi,

Its not possible to get the original p-value at present as they are corrected for multiple-testing as soon as they are generated and this process is not optional in the present implementation of the software. To get the original p-values, the BSprepare function code need to be modified.

Thanks.

Hi Kamal,

Thank you for your answers.

I want to get the original p-values because the input data is so big (about 20G) that I split it to speed up. When I combined the result of every part , the output corrected p-values is not right. Do you have any other suggestions for me or is there a paramete for BSprepare() to speed up?

Thanks.
