WebApr 3, 2024 · A random seed is used to ensure that results are reproducible. In other words, using this parameter makes sure that anyone who re-runs your code will get the exact same outputs. Reproducibility is an extremely important concept in data science and other fields. Lots of people have already written about this topic at length, so I won’t discuss ... http://www.idata8.com/rpackage/Seurat/FindClusters.html
WebThe FindClusters function implements the procedure, and contains a resolution parameter that sets the ‘granularity’ of the downstream clustering, with increased values leading to a greater number of clusters. We find that setting this parameter between 0.6-1.2 typically returns good results for single cell datasets of around 3K cells.
