This study introduces a novel data analysis method for flow cytometry, enabling microcomputers to process complex, multi-dimensional data efficiently. The technique significantly reduces data size and speeds up analysis for multiparameter datasets.

Area of Science:

  • Biotechnology
  • Computational Biology
  • Data Science

Background:

  • Flow cytometry generates high-dimensional data, posing challenges for analysis on microcomputers.
  • Existing methods often require substantial memory and processing power, limiting accessibility.

Purpose of the Study:

  • To develop an efficient data analysis method for flow cytometry suitable for microcomputers.
  • To reduce memory requirements and increase the speed of multiparameter data analysis.

Main Methods:

  • A novel coding technique modifies array vector mapping to represent multi-parameter coordinates as single numbers.
  • Code numbers are ranked, and their frequencies are calculated.
  • Integer arithmetic is used to decode coordinates, which are then packed with frequency data into 16-bit words.

Main Results:

  • The method enables handling up to eight-dimensional flow cytometry data on microcomputers with limited memory (28K addressable + 32K non-addressable).
  • A five-dimensional dataset analysis demonstrated significant space saving and efficient extraction of histograms and bivariate distributions.
  • The technique allows for rapid appreciation of multiparameter data and analysis on microcomputers.

Conclusions:

  • This data analysis method offers a practical solution for microcomputer-based flow cytometry.
  • It enhances the speed and accessibility of multiparameter data analysis, overcoming hardware limitations.
  • The technique facilitates broader use of flow cytometry in research settings with limited computational resources.
