title: Sorting real-time fluorescence and deformability cytometry (soRT-FDC) - manuscript data

description: This dataset contains results presented in <i>Nawaz, Urbanska, Herbig</i> et al manuscript entitled ‘<b>Using real-time fluorescence and deformability cytometry and deep learning to transfer molecular specificity to label-free sorting</b>’ available on bioRxiv (https://doi.org/10.1101/862227) and includes: (i) 29 '*.rtdc' files containing measurements performed with real time fluorescence and deformability cytometry [1,2] (ii) 1 '*.fcs' file containing a measurement performed with a standard flow cytometer (BD LSR II, BD Biosciences) (iii) 1 '*.xlsx' file containing results from AFM-based indentation experiments. Sorting real-time fluorescence and deformability cytometry (soRT-FDC) is a robust sorting platform, combining image-based morphological cell analysis with mechanical characterisation and subsequent active sorting by feeding real-time fluorescence and deformability cytometry (RT-FDC) [2] information to a down-stream SSAW-based cell sorter [3]. Each filename of this dataset starts with the name of the figure to which the datafile corresponds. The measured samples are briefly described below. The 'Initial' measurements refer to the samples used for sorting, and the 'Target' measurements to the samples collected in the target outlet after sorting. For more detailed description of samples please refer to the manuscript. The '*.rtdc' files are HDF5 files and can be analysed using a Python library called dclab [4], or a software called Shape-Out [5]. They can also be opened using other HDF viewer programs.
