Abstract
A system for performing quality control for nucleic acid sample sequencing is disclosed. The system comprises a set of solid supports, each solid support having attached thereto a plurality of nucleic acid sequences, wherein the set comprises plural groups of solid supports and each group contains solid supports having the same nucleic acid sequences attached thereto. The nucleic acid sequences of each group differ from each other. The nucleic acid sequences are synthetically derived, and the nucleic acids sequences are designed such that the nucleic acid sequences produce a predefined pattern of detectable signals during a sequencing run. A method of preparing a quality control for performing nucleic acid sample sequencing, a method of validating a nucleic acid sequencing instrument during a nucleic acid sequencing experiment, and a method of processing nucleic acid sequencing data during a nucleic acid sequencing experiment are also disclosed.
