Cytobank, FlowJo and FCS Express can be used for basic analysis such as bivariate plots, histogram overlays, heatmaps and dose response.Cytobank and FlowJo have plugins, which offer user-friendly versions of clustering algorithms such as ViSNE/tSNE, SPADE, and Citrus …
The standard C++ BH-tSNE implementation that we used to optimize t-SNE parameters only utilizes a single processor core and requires considerable computation time. We thus adopted a recently developed multicore modification of Barnes-Hut t-SNE24 to implement our proposed optimization … See more The t-SNE algorithm can be guided by a set of parameters that finely adjust multiple aspects of the t-SNE run19. However, cytometry data analysis software often locks … See more In order to determine the cause of the difference in cluster resolution between the “standard” and “extended” t-SNE runs, we examined the behavior of KLD (Kullback-Leibler divergence, see Methods) over the … See more The step size in t-SNE gradient descent is updated at each iteration per Jacobs adaptive learning rate scheme22. This method increases the learning rate in directions in which … See more Once we found EE to be crucial for map optimization, we next examined if the value of the EE factor α (EEF) can also be tuned to improve the results of t-SNE. We made α user-accessible in our C++ t-SNE code since it is hard … See more WebCyTOF Assays Most of the same techniques and reporter molecules can be used in CyTOF assays as in fluorescence flow cytometry.
