This study formalizes the "decoding problem" in smart-pooling assays for identifying rare positives. An exact algorithm, interpool, is presented to efficiently solve this problem, aiding high-throughput screening analysis.

Area of Science:

  • Bioinformatics
  • Computational Biology
  • Genomics

Background:

  • High-throughput screening often uses binary assays to detect rare positive samples.
  • Smart-pooling strategies can reduce the number of tests and correct for experimental noise.
  • Interpreting pooled assay results requires solving the 'decoding problem' to identify individual positives, a task that is not well-formalized.

Purpose of the Study:

  • To formally define the 'decoding problem' in the context of smart-pooling assays.
  • To develop and present an exact algorithm for solving the decoding problem.
  • To demonstrate the algorithm's utility in analyzing experimental data from high-throughput projects.

Main Methods:

  • Combinatorial formalization of the decoding problem.
