Stream

Definition

In the context of single-cell transcriptomics, a stream refers to a continuous flow of data or biological samples that are processed in real-time. This concept is crucial for efficiently analyzing gene expression at the individual cell level, allowing researchers to capture dynamic changes and variations in cellular responses during experiments.
