Also referred to as a SNP Manifest, this is a file containing the
SNP-to-beadtype mapping, as well as all SNP annotations. For the
Infinium assay, this is a *.bpm file in binary format.
What is a cluster file?
The cluster file contains the mean (R) and standard deviation (theta)
of the cluster positions, in normalized coordinates, for every
genotype, for every SNP. The cluster file also includes cluster score
information, as well as the allele frequencies from the training set
used to generate the cluster file. A cluster file is required for
KaryoStudio. Illumina provides a standard cluster file for each
product. Alternatively, customers may generate their own cluster file.
