Hello everybody, I have problems in loading files with ChAMP. In particular I hve proble with the pd file (samplesheet), I get back this in R:
[ Section 1: Read PD Files Start ] CSV Directory: C:/Users/utente/methylation_CLL1/Samplesheet_2022-282-ILL_Epic_N=34 (2).csv Find CSV Success Reading CSV File Your pd file contains NO Array(Sentrix_Position) information. Your pd file contains NO Slide(Sentrix_ID) information. There is NO Pool_ID in your pd file. There is NO Sample_Plate in your pd file. There is NO Sample_Well in your pd file. Error in champ.import(directory, arraytype = arraytype) : Error Match between pd file and Green Channel IDAT file.
It says that there is no Sentirx_ID and Sentrix_Position, but actually they are present in my csv file (as all the other info requested. And the I do not understand why there is no match between pd file and IDAT file.
Can you help me please?
