Package picard.arrays.illumina
Class IlluminaAdpcFileWriter
java.lang.Object
picard.arrays.illumina.IlluminaAdpcFileWriter
- All Implemented Interfaces:
AutoCloseable
A class to encompass writing an Illumina adpc.bin file.
This file is used as input to verifyIDIntensity, a contamination checking tool for Illumina Genotyping Arrays.
Here is the format of the file
The file size is (16 byte offset) + (18 bytes) * # INDS * SNP
Note that I do not know what the header (16 bytes) should contain. verifyIDIntensity, does not care, so we are putting garbage in there now. I presume it *should* contain the number of probes (at a minimum)
Each genotype is ordered in the following way. (ind1-snp1) - (ind1-snp2) - (ind1-snp3) ... (ind1-snpN) (ind2-snp1)
The 18 bytes are composed of the following information.
2-short - A intensity 2-short - B intensity 4-float - A normalized intensity 4-float - B normalized intensity 4-float - GC score : clustering confidence 2-short - genotype value : 0 (AA) 1 (AB) 2 (BB) 3 (NN)
