Purpose of the Study:

  • To address the lack of data analysis and visualization tools for image-based high-content RNAi screening.
  • To introduce iScreen, an R package designed for statistical modeling and visualization of such data.

Main Methods:

  • Development of the iScreen R package.
  • Utilizing statistical modeling for the analysis of image-based high-content screening data.
  • Implementing visualization techniques for complex cellular phenotypes.

Main Results:

  • The iScreen package provides essential tools for analyzing image-based high-content RNAi screening experiments.
  • Two case studies demonstrated the package's capability and efficiency in handling complex phenotypic data.
  • The package facilitates genome-wide functional annotation and aids in drug and target discovery.

Conclusions:

  • iScreen effectively supports the statistical modeling and visualization of image-based high-content RNAi screening data.
  • The availability of iScreen enhances the utility of high-content screening in biological research and discovery.
