By default nf-core/taxprofiler will only provide the `.log` file if host removal is turned on. You will only have a `.bam` file if you specify `--save_hostremoval_bam`. This will contain _both_ mapped and unmapped reads. You will only get FASTQ files if you specify to save `--save_hostremoval_unmapped` - these contain only unmapped reads. Alternatively, if you wish only to have the 'final' reads that go into classification/profiling (i.e., that may have additional processing), do not specify this flag but rather specify `--save_analysis_ready_reads`, in which case the reads will be in the folder `analysis_ready_reads`.

The results directory will contain the 'final' processed reads used as input for classification/profiling. It will _only_ include the output of the _last_ step of any combinations of preprocessing steps that may have been specified in the run configuration. For example, if you perform the read QC and host-removal preprocessing steps, the final reads that are sent to classification/profiling are the host-removed FASTQ files - those will be the ones present in this directory.
|

|

> ⚠️ If you turn off all preprocessing steps, then no results will be present in this directory. This happens independently for short- and long-reads. I.e. you will only have FASTQ files for short reads in this directory if you skip all long-read preprocessing.
