Which files are required and optional when creating a GenomeStudio project?

Required files for creating a GenomeStudio project:

  • Red and green intensity data (*.idat) files for each sample; are contained in scan folders with barcode names.

  • Manifest file (*.bpm) containing Bead IDs and Single Nucleotide Polymorphism (SNP) information for each marker on the array.

    • A commercial BeadChip manifest can be downloaded from the product-specific Illumina Support page under Product Files.

    • A consortium/custom BeadChip manifest can be downloaded from MyIllumina using a custom product file search.

  • For methylation projects, the Sentrix Descriptor File (*.sdf) inside the scan folder is required.

Optional files for creating a GenomeStudio project:

  • Cluster file (*.egt) containing expected cluster positions for each marker on the array.

    • A commercial BeadChip cluster file can be downloaded from the product-specific Illumina Support page under Product Files.

    • A consortium/custom BeadChip cluster file is not available on the website and must be generated using GenomeStudio.

  • Sample sheet (*.csv) containing user-specified sample information.

  • A sample sheet template can be downloaded from the product-specific Illumina Support page under Support Files.

  • For methylation projects, a cluster file is not used.
