Smith:WGS - what about storage of the data? They do 5kb mate-pairs and 2GB may be sufficient. They look for HPV integration #NGDx15
3:30pm August 18th 2015 via Hootsuite
Smith: QIAGEN integrated end-to-end solution. But the middle box - 'not a platform at all'. #NGDx15
3:28pm August 18th 2015 via Hootsuite
