This module estimates copy number variation (CNV) of one or more tumor samples by comparing methylation levels at these locations to a reference set of \"normal\" methylation profiles.\n\n### Requires:\n- Tumor methylation profiles: [sample]_Grn.idat and [sample]_Red.idat\n- A set of control methylation profiles in the same format.\n\n## References\nMah CK, Mesirov JP, Chavez L.
