Hi , Can anyone guide me on some open source tools for genotype analysis of Illumina microarray data? As I understand Illumina Infinium microarray data have .idat file format. Are these files encrypted? Where can I find some sample files? Thanks in advance.

I don't have experience with this type of analysis, but a quick google search directs me to argyle. Have you tried this already? There is a vignette with examples available.

Great thanks for the information,Benn ! Infact, even I am new to genotype analysis and did find some R packages for the same but was unsure of which software to select. Are you aware of any decrypting software related to microarray data?

Try limma's read.idat function, see if it works for you.
