But, before we do that, we will export all of the necessary meta-data from our Seurat object that is needed for our RNA Velocity object. This includes: Filtered Cell Ids UMAP or TSNE coordinates Clusters (Optional) Cluster Colors (Optional) ...
在上文中,我们定义了RNA velocity 为v(t)=dsdt=u(t)−γs(t)假设在t=0时刻,未剪接的mRNA...
