Hi everyone!

I have 2 questions regarding using "sesame" package for methylation array data analysis.

1) can "sesame" be used for Illumina 450k beadchips array or is it only for EPIC array?

2) I have a problem when I tried to use "sesame" for the 450K beachips array methylation data:

library(sesame)

des_dir sesameDataCacheAll()

| to retrieve and cache needed sesame data.

I follow the instruction (run the two suggested functions) but it did not help.

Could anyone kindly help me to overcome with the step?

Thank you all in advance!
