Reqs for Quality Control

• GeomxTools shall provide the ability to perform Segment QC on the data by performing Technical Signal quality Control which assesses the quality sequencing of each segment.
• GeomxTools shall provide the ability to perform Segment QC on the data by performing Technical background quality Control which flags the samples based on the negative controls.
