Export AnnData Expression Matrix
For export in AnnData format (h5ad), a number of options can be specified:
- Cell format. Can be specified to include both the sample and barcode. Hover the mouse over this setting to see the possible options. Often the barcode in itself is sufficient as a unique identifier of cells. However, when an expression matrix contains multiple samples, the cell format must also include the sample, otherwise the export will fail.
- Use compression. Select among gzip, zip or no compression which is default.
- Output file name. Shows the name of the file. This can be customized by changing the default pattern in Custom file name.
The AnnData exporter produces an hdf5 file with:
- Feature names written at
var/index
. - Feature ids written at
var/gene_ids
.
