CuratedAtlasQueryR

Lifecycle:maturing

CuratedAtlasQuery is a query interface that allow the programmatic exploration and retrieval of the harmonised, curated and reannotated CELLxGENE single-cell human cell atlas. Data can be retrieved at cell, sample, or dataset levels based on filtering criteria.

Harmonised data is stored in the ARDC Nectar Research Cloud, and most CuratedAtlasQuery functions interact with Nectar via web requests, so a network connection is required for most functionality.

Usage

The API has delivered more than 15Tb of data to the community in the first year. Thanks!

Extract the counts as a Seurat object

This convert the H5 SingleCellExperiment to Seurat so it might take long time and occupy a lot of memory depending on how many cells you are requesting.

Save your SingleCellExperiment

The returned SingleCellExperiment can be saved with two modalities, as .rds or as HDF5.

Saving as RDS (fast saving, slow reading)

Saving as .rds has the advantage of being fast, andd the .rds file occupies very little disk space as it only stores the links to the files in your cache.

However it has the disadvantage that for big SingleCellExperiment objects, which merge a lot of HDF5 from your get_single_cell_experiment, the display and manipulation is going to be slow. In addition, an .rds saved in this way is not portable: you will not be able to share it with other users.

single_cell_counts |> saveRDS("single_cell_counts.rds")

Saving as HDF5 (slow saving, fast reading)

Saving as .hdf5 executes any computation on the SingleCellExperiment and writes it to disk as a monolithic HDF5. Once this is done, operations on the SingleCellExperiment will be comparatively very fast. The resulting .hdf5 file will also be totally portable and sharable.

However this .hdf5 has the disadvantage of being larger than the corresponding .rds as it includes a copy of the count information, and the saving process is going to be slow for large objects.

Obtain Unharmonised Metadata

Various metadata fields are not common between datasets, so it does not make sense for these to live in the main metadata table. However, we can obtain it using the get_unharmonised_metadata() function. This function returns a data frame with one row per dataset, including the unharmonised column which contains unharmnised metadata as a nested data frame.

harmonised <- metadata |> dplyr::filter(tissue == "kidney blood vessel")
unharmonised <- get_unharmonised_metadata(harmonised)
unharmonised
#> # A tibble: 1 × 2
#>   file_id                              unharmonised   
#>   <chr>                                <list>         
#> 1 dc9d8cdd-29ee-4c44-830c-6559cb3d0af6 <tbl_dck_[,14]>

Through harmonisation and curation we introduced custom column, not present in the original CELLxGENE metadata

  • tissue_harmonised: a coarser tissue name for better filtering
  • age_days: the number of days corresponding to the age
  • cell_type_harmonised: the consensus call identity (for immune cells) using the original and three novel annotations using Seurat Azimuth and SingleR
  • confidence_class: an ordinal class of how confident cell_type_harmonised is. 1 is complete consensus, 2 is 3 out of four and so on.
  • cell_annotation_azimuth_l2: Azimuth cell annotation
  • cell_annotation_blueprint_singler: SingleR cell annotation using Blueprint reference
  • cell_annotation_blueprint_monaco: SingleR cell annotation using Monaco reference
  • sample_id_db: Sample subdivision for internal use
  • file_id_db: File subdivision for internal use
  • sample_: Sample ID
  • .sample_name: How samples were defined

RNA abundance

The raw assay includes RNA abundance in the positive real scale (not transformed with non-linear functions, e.g. log sqrt). Originally CELLxGENE include a mix of scales and transformations specified in the x_normalization column.

The cpm assay includes counts per million.
