WebIn this section we will use the ComBat-Seq tool in R (Bioconductor) to demonstrate the principles and application of batch correction. Due to the way our test data was generated (at a single center, at one time, with consistent methodology) we do NOT expect batch effects in these data. Therefore we will use a different (but highly related) dataset to …

WebGraph clustering ¶. The procedure of clustering on a Graph can be generalized as 3 main steps: 1) Build a kNN graph from the data. 2) Prune spurious connections from kNN graph (optional step). This is a SNN graph. 3) Find groups of cells that maximizes the connections within the group compared other groups. WebThe nearest neighbours for each batch are then merged to create a final list of neighbours for the cell. Aligns batches in a quick and lightweight manner.
