GitHub Gist: star and fork FloWuenne's gists by creating an account on GitHub.
Oct 17, 2020 · The data were processed in the same way as CDRCC. Original sequencing data matrices from CellRanger (version 3.0.2) were imported to R (version 3.5.2-Eggshell Igloo), and integrated with Seurat R package (version 2.3.4) 53. To guarantee the quality of sequencing, the cells with <200 or > 5000 genes were depleted from the original data. Halo 3 reddit
Seurat has implemented a “Weighted Nearest Neighbor” approach that will combine the nearest neighbor graphs from the RNA data with the antibody data. The algorithm will calculate relative weights for the RNA or the Protein data for each cell and use these new weights to constuct a shared graph. May 19, 2020 · Only nondiseased lungs (indicated as donor or control) were used for analysis. Precomputed R objects were loaded into Seurat 3.1.4 and expression of TLR4 was visualized using FeaturePlot command. Two-photon microscopy. A custom-built 2-photon microscope running ImageWarp acquisition software (A&B Software) was used for time-lapse imaging.
seurat featureplot scale, Seurat continues to use tSNE as a powerful tool to visualize and explore these datasets. While we no longer advise clustering directly on tSNE components, cells within the graph-based clusters determined above should co-localize on the tSNE plot. The Seurat R package (version 2.2) was used for graph-based clustering and visualizations. All functions mentioned are from the Seurat R package (version 2.2) or the standard R version 3.4.2 package and were used with default parameters unless otherwise noted.
