You can cite the scverse publication as follows: Here we will use a reference PBMC dataset that we get from scanpy datasets and classify celltypes based on two methods: As you can see, the main celltypes are the same, but dendritic cells are mainly predicted to cluster 8 by ingest and the proportions of the different celltypes are different. EpiScanpy is the epigenomic extension of the very popular scRNA-seq analysis tool Scanpy Hi Pavlin, have you thought about integrating openTSNE into scanpy? Scanpy has a smart internal setup where the same kNN graph is used for various downstream analysis tasks such as dimensionality reduction or clustering. [] (optional) I have confirmed this bug exists on the master branch of scanpy. Sign up Toggle navigation. Also, could potentially add a different key in obsm, since I don't think you can transform data into the existing space and this may conflict with ingest (any thoughts @Koncopd?). Write better code with AI Security. Using the function in the Spatial tutorial at the scanpy website we will calculate normalized cosine distances between the two datasets and sc. Fixes `AttributeError: 'Ingest' object has no attribute '_pca_use_hvg'` · scverse/scanpy@7287050 I found this problem too. Readme License. pca will zero center all genes so that the first PC doesn't just capture mean variation, but scaling goes beyond that. ingest(spatial_data, sc_data, obs='unified_clusters') The issue I am running into is that the ingest function forces an identity onto cells even though the confidence of that identity is probably very low.
