The Hashtag demultiplexing task is an implementation of the algorithm used in Stoeckius et al. 20181 for multiplexing cell hashing data. The task adds cell-level attributes "Sample of origin" and "Cells in droplet".
Prerequisites for running Hashtag demultiplexing
To run Hashtag demultiplexing, your data must meet the following criteria:
...
If you want to specify each Sample of origin instead of using the hashtag feature ID, you will need to prepare a Sample ID .csv file with the hashtag feature ID in the first column and the corresponding sample ID in the second column.
Running Hashtag demultiplexing
- Click the Normalized counts data node for your cell hashing data
- Click Hashtag demultiplexing in the Pre-analysis tools section of the toolbox
- Click Browse to select your Sample ID file (Optional)
- Click Finish to run
...
It is also possible to use the Merge matrices task to combine your data types and attributes.
