Hi Biostars,

I'm looking for a package/tool that can perform DMR calling of Infinium array data after meta-analysis. All the packages I've seen so far (eg:DMRcate and bumphunter) require the original matrices of m- or beta-values which won't work for us.

We tried combp from the ENmix package but that gave an error during execution so we are lookig for more options.

We posted the combp error to a different forum https://support.bioconductor.org/p/p132476/

Error in if (any(p.stouffer > 0.05)) { : 

  missing value where TRUE/FALSE needed

Thanks!
