# Filtering

Partek Flow has the flexibility to subsample your data for further downstream analyses. Filter data by:

* [Filter features](https://help.connected.illumina.com/partek/partek-flow/user-manual/task-menu/filtering/filter-features)
* [Filter groups (samples or cells)](https://help.connected.illumina.com/partek/partek-flow/user-manual/task-menu/filtering/filter-groups-samples-or-cells)
* [Filter barcodes](https://help.connected.illumina.com/partek/partek-flow/user-manual/task-menu/filtering/filter-barcodes)
* [Split by attribute](https://github.com/illumina-swi/partek-docs/blob/main/docs/partek-flow/user-manual/task-menu/filtering/split-by-attributes.md)
* [Downsample Cells](https://github.com/illumina-swi/partek-docs/blob/main/docs/partek-flow/user-manual/task-menu/filtering/downsample-cells.mds)
