 #### Read Processing

-Raw sequencing read processing in the form of adapter clipping and paired-end read merging can be activated via the `--perform_shortread_clipmerge` or `--perform_longread_clip` flags.
+Raw sequencing read processing in the form of adapter clipping and paired-end read merging can be activated via the `--perform_shortread_qc` or `--perform_longread_qc` flags.

 It is highly recommended to run this on raw reads to remove artefacts from sequencing that can cause false positive identification of taxa (e.g. contaminated reference genomes) and/or skews in taxonomic abundance profiles.

 There are currently two options for short-read preprocessing: `fastp` or `adapterremoval`.

-For adapter clipping, you can either rely on tool default adapter sequences, or supply your own adapters (`--shortread_clipmerge_adapter1` and `--shortread_clipmerge_adapter2`)
-By default, paired-end merging is not activated and paired-end profiling is performed where supported otherwise pairs will be independently profiled. If paired-end merging is activated you can also specify whether to exclude unmerged reads in the reads sent for profiling (`--shortread_clipmerge_mergepairs` and `--shortread_clipmerge_excludeunmerged`).
-You can also turn off clipping and only perform paired-end merging, if requested. This can be useful when processing data downloaded from the ENA, SRA, or DDBJ (`--shortread_clipmerge_skipadaptertrim`).
-Both tools support length filtering of reads and can be tuned with `--shortread_clipmerge_minlength`. Performing length filtering can be useful to remove short (often low sequencing complexity) sequences that result in unspecific classification and therefore slow down runtime during profiling, with minimal gain.
