This is a README for the imaging flow cytometry protocol For more information, see H. Hennig, P. Rees, T. Blasi, L. Kamentsky, J. Hung, D. Dao, A.E. Carpenter, and A. Filby. An open-source solution for advanced imaging flow cytometry data analysis using machine learning. Methods, in press (2016) Step 1: Use python app (or Matlab script) to read cif file and generate image tiles. input: example.cif output: Step1_Matlab_tiling.zip Note: This cif file serves as a quick example, it contains only a very small number of images. Step 2: Segment cells and extract featurs with Cellprofiler input: Step2_input_tiled_tifs.zip output: Step2_CP_output.zip Note: The input images are Jurkat cells, the data set was analyzed in the article above (Hennig et al., Methods, 2016), where a label-free prediction of the cell cycle is demonstrated. The corresponding CellProfiler pipeline to extract features is provided.
