WebAug 18, 2024 · In your case, this will simply subset sample_one to observations present in both sample_one and tsne. The columns "initial_size", "initial_size_unspliced" and "initial_size_spliced" are added when calling scvelo.utils.merge. These are the counts per cell prior to subsetting, i.e. the initial size of the cell. I'd do something along the lines of. WebAs expected, the 3-D embedding has lower loss. View the embeddings. Use RGB colors [1 0 0], [0 1 0], and [0 0 1].. For the 3-D plot, convert the species to numeric values using the categorical command, then convert the numeric values to RGB colors using the sparse function as follows.
