In GeneSpring, Affymetrix and Illumina data files are supported as standard formats.
Data files in other formats can be converted to the Standard Illumina format and imported into GeneSpring to perform the CNV analysis.
The mandatory columns to be present in the data file to create the technology are dbSNPID, Chromosome Name, Chromosome Position, CNV regions in the same order.
From the data file, GeneSpring directly uses the following values for each sample.
log R - Provides the log (base 2) ratio of the normalized R value for the SNP divided by the expected normalized R value.
BAF (B allele Frequency) Copy Number values and their confidences Genotype of the subject SNP for the sample along with the score.
