Symphony pre-built single-cell reference atlases

Pre-built Symphony reference objects that can be downloaded and used to map new query datasets.

The Symphony algorithm is used to perform reference mapping to these atlases.

To read in a reference into R, one may simply execute: reference = readRDS('path/to/reference_name.rds')

Note: To be able to map query datasets into the reference UMAP coordinates, you must also download the corresponding 'uwot_model' file and set the reference$save_uwot_path.
