Hi,

 

I'm trying to analyse my Illumina methylation EPIC microarray data using RnBeads and I get the following error when i do:

 

rnb.run.analysis(dir.reports=reportDir, sample.sheet=sampleSheet, data.dir=idatDir, data.type="infinium.idat.dir")

Error in logger.error(txt) : 

  Some IDAT files are not present in the supplied base directory, for instance 200357150012_Red.idat, 200357150012_Grn.idat, 200357150012_Red.idat, 200357150012_Grn.idat, 200357150012_Red.idat, 200357150012_Grn.idat

 

I have rechecked my folder that holds the .idat files and I have all the necessary files in there so I'm not sure why its giving me this error.

 

Any help is highly appreciated.

 

Thanks,

Rasi
