The number of unique genes detected in each cell. Low-quality cells or empty droplets will often have very few genes. Cell doublets or multiplets may exhibit an aberrantly high gene count.
WebAug 21, 2024 · Once these have all been converted to seurat objects (which all worked as above without issues) I proceed to merge them. I need to run batch correction, however, because there are 11 objects. i much prefer the 'object.split' method of splitting the data before running anchor and integration methods as oppose to doing them all individually. WebIf the reference cell isn't found within the first k.filter neighbors, remove the anchor. Assign each remaining anchor a score. For each anchor cell, determine the nearest k.score anchors within its own dataset and within its pair's dataset.
WebSeurat can help you find markers that define clusters via differential expression. By default, it identifes positive and negative markers of a single cluster (specified in ident.1), compared to all other cells. FindAllMarkers automates this process for all clusters, but you can also test groups of clusters vs. each other, or against all cells. Web9.3 Cannonical Correlation Analysis (Seurat v3). The Seurat package contains another correction method for combining multiple datasets, called CCA.However, unlike mnnCorrect it doesn’t correct the expression matrix itself directly. Instead Seurat finds a lower dimensional subspace for each dataset then corrects these subspaces. Also different …
