Упражнение 2 — Samples/year

Упражнение 3 — Капекс genomics center

Illumina NovaSeq 6000 × 4 + X × 8 = 7 млрд
PacBio Sequel IIe × 2 + Nanopore PromethION × 4 = 2 млрд
HPC cluster Dell PowerEdge 100 nodes + GPU A100 × 50 = 4 млрд
Storage Dell EMC Isilon 10 PB + tape 50 PB = 1.5 млрд
Sample prep robotics Hamilton STAR + Beckman + QIAcube = 0.8 млрд
QC + biobank LN2 + cold storage = 0.7 млрд
Building 3000 м² + cleanroom + проектирование 4% + insurance = 2 млрд
