# Post-alignment tools

Post-alignment tools involve tasks that can be performed on aligned data. These are typically used in preparing aligned data for other downstream analyses, such as DNA-Seq or RNA-Seq analysis.

To invoke Post-alignment tools, click on an **Aligned reads** data node (Figure 1). There are three functions available in Post-alignment tools:

* [Filter alignments](/partek/partek-flow/user-manual/task-menu/post-alignment-tools/filter-alignments.md)
* [Convert alignments to unaligned reads](/partek/partek-flow/user-manual/task-menu/post-alignment-tools/convert-alignments-to-unaligned-reads.md)
* [Combine alignments](/partek/partek-flow/user-manual/task-menu/post-alignment-tools/combine-alignments.md)
* [Deduplicate UMIs](/partek/partek-flow/user-manual/task-menu/post-alignment-tools/deduplicate-umis.md)
* [Downscale alignments](/partek/partek-flow/user-manual/task-menu/post-alignment-tools/downscale-alignments.md)
