| Scan protocol |
All slides were scanned with the Agilent DNA Microarray Scanner with Surescan High-Resolution technology and data extracted using the Agilent Feature Extraction Software v. 10.5.1.1 as described in the Agilent Oligo aCGH protocol.
|
| Data processing |
Agilent Feature Extraction Software (version 10.5.1.1) and Genomic Workbench software (Agilent Technologies Inc., Palo Alto, California, USA). Aberrant DNA copy number intervals identified using the Aberration Detection Method 2 (ADM-2), default threshold setting 6.0, and Fuzzy Zero correction algorithm applied. To ensure the exclusion of very low or very small aberrations, we added a custom-made aberration filter defining a region with a copy number aberration as a region with minimum five probes gained/lost and with minimum absolute average log2 ratio of 0.2 (gain) or -0.2 (loss). A loss defined as homozygous when the log2 ratio was lower than -1, and a gain was regarded as high level amplification when the log2 ratio was higher than 1.
