I'm a final semester Master's student in bioinformatics, working on Copy number variation analysis, in my dissertation project.

I'm using leukemia samples and my sample has been processed in Illumina infinium cytoSNP 850k beadchip array.

I'm exploring an open source tool - iPsychCNV ( http://ibp.nordisknettv.dk/iPsychCNV/ ) to analyse the cnv. While it has a great documentation, I'm not able to figure out what should be the input file format?

I've GTC/IDAT files ( from illumina 850k cytoSNP array )with me. If anybody has worked with this tool before, it would be great help to know how you proceeded with the file format. Thank you in advance
