This step reduces noise in the data and can improve the tSNE algorithm output. Cleaning up your data – The best analyses begin with cleaning up raw data to exclude doublets, debris, and dead cells.This section will briefly cover a few key points in the area of preparing your data. While tSNE is a powerful visualization technique, running the algorithm is computationally expensive, and the output is sensitive to the input data. The native platforms in FlowJo (such as tSNE) do not require R.It can be accessed and run through the Populations menu (Workspace tab –> Populations band). įlowJo v10 has an extremely powerful native platform for running tSNE. Please see the references section for more details on the tSNE algorithm and its potential applications. It can be used independently to visualize an entire data file in an exploratory manner, as a preprocessing step in anticipation of clustering, or in other related workflows. Importantly, tSNE can be used as a piece of many different workflows. The tSNE-generated parameters are optimized in such a way that observations/data points which were close to one another in the raw high dimensional data are close in the reduced data space. T he tSNE platform computes two new derived parameters from a user defined selection of cytometric parameters. TSNE is an unsupervised nonlinear dimensionality reduction algorithm useful for visualizing high dimensional flow or mass cytometry data sets in a dimension-reduced data space. T-Distributed Stochastic Neighbor Embedding (tSNE) is an algorithm for performing dimensionality reduction, allowing visualization of complex multi-dimensional data in fewer dimensions while still maintaining the structure of the data.
