Automate cell type annotation for scRNA-seq data by applying pre-trained logistic regression models to assign labels to individual cells. This approach enables faster and more reproducible biological discoveries.

Cell annotation requires normalized and log1p-transformed AnnData objects as input. You must provide preprocessed single-cell RNA sequencing data in this specific format to ensure accurate model predictions.

You can generate cluster-level consensus labels for scRNA-seq cell types using majority voting. This provides biologically coherent annotations alongside per-cell labels and confidence scores.

Celltypist identifies immune cells in a PBMC dataset by utilizing standardized pan-immune models like Immune_All_Low.pkl. It quickly assigns cell type labels to individual cells, identifying major immune lineages and subtypes.

You need scanpy, anndata, and celltypist Python packages installed to perform single-cell RNA sequencing annotation. These dependencies are required to handle the normalized log1p-transformed input objects.

The best way to annotate immune lineages across different tissue types is using pre-trained logistic regression models. These models support various tissue-specific and pan-immune atlases for comprehensive scRNA-seq analysis.
