Illumina offers several different types of product data files for our Bead Array technology-based genotyping, gene expression, and methylation assays. Available for standard and some custom arrays, these files supply information on SNP or probe content, as well as bead location and cluster position. You will need a valid iCom account to access some of these files.

DMAP Files

These BeadChip decode files (.dmap) are required to scan a BeadChip on your BeadArray Reader, iScan, HiScan, or HiScanSQ system. The reader uses the dmap files to generate intensity data files (.idats) that will feed into GenomeStudio Analysis software.


The DMAP Download Client software provides a way to electronically download your DMAP files. We recommend that you download the files soon after receiving your BeadChips.


DMAP files are retained in Illumina’s system for only 30 days after your first download or until the expiration date on the BeadChip package, whichever comes first.

Manifest Files

All Manifest files are required for data analysis in Illumina's GenomeStudio software. Manifest files provide a description of the SNP or probe content on a standard BeadChip or in an assay product. They are available as a (.bpm) file for Infinium BeadChips, (.opa) file for GoldenGate assay pools, (.dap) file for DASL assay pools, or (.bgx) file for gene expression arrays, and are provided for both standard and custom arrays.

For BeadChips, the (.bpm) files and GoldenGate (.opa) files are also used by the Infinium LIMS Project manager to track samples throughout analysis.

For Illumina LIMS users, manifest file downloads will also include an (.xml) file that is required for processing BeadChips in LIMS.

Cluster Files

Cluster files (.egt) are used when analyzing data to make genotype calls. These files are provided for standard Infinium BeadChip products, but are not provided for any custom GoldenGate or VeraCode OPA or custom or consortium-developed iSelect BeadChips.

Use these files to create genotype calls and analyze data in Illumina's GenomeStudio software.

Standard Beadchip Products

If you need assistance at any time, contact Illumina Technical Support.

XML Files

Known as product definition files, these files are required by Illumina LIMS to identify and accession products into the system. The appropriate .xml definition file is automatically included in the download of an Infinium BeadChip manifest file (.bpm) or GoldenGate manifest file (.opa). Product definition files are provided for catalog and custom genotyping products.
