-[UMI-tools](https://github.com/CGATOxford/UMI-tools) deduplicates reads based on unique molecular identifiers (UMIs) to address PCR-bias. Firstly, the UMI-tools `extract` command removes the UMI barcode information from the read sequence and adds it to the read name. Secondly, reads are deduplicated based on UMI identifier after mapping as highlighted in the [UMI-tools dedup](#umi-tools-dedup) section.

-After extracting the UMI information from the read sequence (see [UMI-tools extract](#umi-tools-extract)), the second step in the removal of UMI barcodes involves deduplicating the reads based on both mapping and UMI barcode information using the UMI-tools `dedup` command. This will generate a filtered BAM file after the removal of PCR duplicates.
+After extracting the UMI information from the read sequence (see [UMI-tools extract](#umi-tools-extract)), the second step in the removal of UMI barcodes involves deduplicating the reads based on both mapping and UMI barcode information. UMI deduplication can be carried out either with [UMI-tools](https://github.com/CGATOxford/UMI-tools) or [UMICollapse](https://github.com/Daniel-Liu-c0deb0t/UMICollapse), set via the `umi_dedup_tool` parameter. The output BAM files are the same, though UMI-tools has some additional outputs, as described above. Either method will generate a filtered BAM file after the removal of PCR duplicates.
