| Method | Sequencing | 
| Analysis | Copy number variations are detected using the SOLiD Human CNV Tool. Regions with poor mappability are filtered out from consideration and a log ratio of coverage is used to determine areas of increased copy number. A Hidden Markov Model converts increased coverage into discrete copy number states. |
