Extracted molecule genomic DNA
Extraction protocol Qiagen Dneasy
Label C-Bio and A-DNP
Label protocol Unique barcodes are affixed to the sample and associated within an internal sample tracking system
 
Hybridization protocol Illumunian infinium process
Scan protocol Illumunian infinium process using iScan
Data processing All the raw data comes from illumina arrays. Illumina also post-processes the data using Bead Studio to create the b-allele-frequency number and log-r-ratio. We use the b-allele-frequency in our analysis.
In some cases the post processing does not provide the b-allele-frequency numbers. In those cases, we calculate radial and theta numbers for each snip. The formulas are radial = sqrt(chX^2+chY^2) theta = arcsine(chY/radial) This is done on per snip bases where chX and chY are the raw counts. If both are 0, the output is not-a-number.
Series supplementary files contain raw X and Y signals only
