This repository contains the code used for data processing and analysis in our manuscript titled "Spatial and single-nucleus trancsriptomic analysis of genetic and sporadic forms of Alzheimer's disease".
TODO: Add a brief intro
- Clean up all notebooks
- Remove all unused code
- Provide basic comments in all scripts
- In each README section, write a short para or few sentences about the analysis.
The raw and processed ST (10X Genomics Visium) and snRNA-seq (Parse Biosciences) datasets have been deposited on the NCBI Gene Expression Omnibus (GEO) at accession number XXXXXX.
- Parse Biosciences snRNA-seq preprocessing scripts
- Human 10X Visium ST preprocessing scripts
- Mouse 10X Visium ST preprocessing scripts
New snRNA-seq data
- Clustering analysis for DSAD and Control data generated in this study
- Format dataset as a Seurat Object
Integration
- Integration with 3 published studies using scANVI
- Subclustering analysis of major cell lineages
- Format integrated dataset as a Seurat Object
Differential cell state analysis
Human dataset
- Load human spaceranger outputs and format as a Seurat Object
- Format human ST dataset as an anndata object, pt1
- Format human ST dataset as an anndata object, pt2
- BayesSpace clustering analysis in the human dataset
Mouse dataset
- Load mouse spaceranger outputs and format as a Seurat Object
- Format mouse ST dataset as an anndata object, pt1
- Format mouse ST dataset as an anndata object, pt2
- BayesSpace clustering analysis in the mouse dataset
Additional plotting
Note:Need to find from Emily's codebase:
- Human ST marker genes
- Human ST condition
- Mouse ST marker genes (?)
All snRNA-seq DEG scripts are there
Make a separate script for the Pseudobulk comparisons that we used for the peer review doc?
