The present technology provides an information processing apparatus including a processing unit that generates a combination list of phosphors with respect to biomolecules on the basis of expression level categories in which a plurality of biomolecules to be used for analysis of a sample is classified on the basis of expression levels in the sample, brightness categories in which a plurality of phosphors usable for the analysis of the sample is classified on the basis of brightness, and correlation information between the plurality of phosphors, in which the processing unit selects the phosphors to be allocated to the biomolecules in the combination list from phosphors belonging to a brightness category associated with an expression level category to which the biomolecules belong.
VISUAL CELL SORTING
The disclosure provides methods, systems and related software, for automated or semi-automated sorting and/or isolating cells with visually distinguishable phenotypes. In some embodiments, the methods comprise providing a plurality cells with a photo-activatable detectable marker in their respective nuclei. The plurality of cells are imaged and, based on the image, the status for one or more visually identifiable phenotypes are determined. Cells determined to have the desired phenotype status are specifically exposed to a light wavelength for a time sufficient to uniquely activate the photo-activatable detectable marker in the individual cells with the desired phenotype status. The cells are then sorted on the basis of the activated detectable marker. The disclosure also provides methods for preparation and isolation of nuclei from fixed, adherent cells for analysis.
Method for Optimal Scaling of Cytometry Data for Machine Learning Analysis and Systems for Same
Aspects of the present disclosure include methods for processing and scaling cytometric data. Methods according to certain embodiments include obtaining cytometric data for a sample, wherein the cytometric data comprises measurements of a plurality of parameters from particles irradiated in the sample flowing in a flow stream; identifying a parameter of interest; specifying positive and negative measurement intervals on the parameter of interest; scaling the cytometric data by transforming the parameter of interest based at least in part on the corresponding specified positive and negative intervals. Systems for practicing the subject methods are also provided. Non-transitory computer readable storage mediums are also described.
FRAMEWORK FOR IMAGE BASED UNSUPERVISED CELL CLUSTERING AND SORTING
A framework that includes a feature extractor and a cluster component for clustering is described herein. The framework supports (1) offline image-based unsupervised clustering that replaces time-consuming manual gating; (2) online image-based single cell sorting. During training, one or multiple cell image datasets with or without ground truth are used to train feature extractor, which is based on a neural network including several convolutional layers. Once trained, the feature extractor is used to extract features of cell images for unsupervised cell clustering and sorting. In addition, additional datasets may be used to further refine the feature extractor after it has been trained.
