Hi,

I use the DSS package to identify DMRs. I has already written a script that worked very well with the first data that I had tested. I wanted to reuse this same script but now I am blocked when using the function "makeBSseqData". I get the following error :

Error in get(name, envir = asNamespace(pkg), inherits = FALSE) :
  object 'normalize_names_replacement_value' not found
Calls: makeBSseqData ... new_GRanges -> IRanges -> names<- -> names<- -> ::: -> get
Execution halted

After some reseach, I have the impression that the problem could be in connection with updates of S4vector but I cannot resolve the problem.

Could someone give me some leads to test ?

Thanks in advance,

Bernadette
