illuminaio

illuminaio parses Illumina IDAT files to extract BeadArray probe-type summary intensities and decrypt proprietary data for downstream genomic analyses such as gene expression profiling.

Key Features:

• IDAT parsing: Parses IDAT files from all Illumina BeadArray platforms, including gene expression arrays.
• Decryption: Decrypts proprietary IDAT files produced by Illumina scanners.
• Intensity extraction: Extracts summary intensities for each probe-type on an array.
• Text conversion: Converts parsed and decrypted data into human-readable text formats.
• Scanner output support: Processes direct output from Illumina scanners in IDAT format.

Scientific Applications:

• BeadArray data processing: Enables processing of BeadArray data for downstream genomic analyses, including gene expression profiling.
• Data sharing and submission: Facilitates conversion of IDAT files into formats suitable for submission to public databases and data sharing.
• Reproducible analysis: Allows independent processing and analysis of Illumina BeadArray data to support transparency and reproducibility.
• Standardization: Supports adoption of IDAT as a standardized exchange format analogous to Affymetrix CEL files.

Methodology:

Parses and decrypts Illumina IDAT binary files to extract summary probe-type intensities and outputs them in human-readable text formats.
