I'm trying to run quality control on the Illumina 450K methylation chip data with the meffil package.
I create the Sample sheet using the following command:
samplesheet <- meffil.create.samplesheet("/path/to/idat/files/", recursive=TRUE)
I add sex and personal id columns and load again with this command:
samplesheet <- meffil.read.samplesheet(base="/path/to/samplesheet/",pattern = "SampleSheet_450K.csv")
I get this error when running the code above:
[read.450k.sheet] Found the following CSV files:  "/.../SampleSheet_450K.csv" Warning message: In FUN(X[[i]], ...) : Could not infer array name for file: /.../SampleSheet_450K.csv
Any advice or clue is more than welcome, is my first time doing this kind of analyses.
Thanks in advance for your help,
