usage: fastp [options] ... 
options:
  -i, --in1                            read1 input file name (string [=])
  -o, --out1                           read1 output file name (string [=])
  -I, --in2                            read2 input file name (string [=])
  -O, --out2                           read2 output file name (string [=])
      --unpaired1                      for PE input, if read1 passed QC but read2 not, it will be written to unpaired1. Default is to discard it. (string [=])
      --unpaired2                      for PE input, if read2 passed QC but read1 not, it will be written to unpaired2. If --unpaired2 is same as --unpaired1 (default mode), both unpaired reads will be written to this same file. (string [=])
      --failed_out                     specify the file to store reads that cannot pass the filters. (string [=])
  -m, --merge                          for paired-end input, merge each pair of reads into a single read if they are overlapped. The merged reads will be written to the file given by --merged_out, the unmerged reads will be written to the files specified by --out1 and --out2. The merging mode is disabled by default.
      --merged_out                     in the merging mode, specify the file name to store merged output, or specify --stdout to stream the merged output (string [=])
      --include_unmerged               in the merging mode, write the unmerged or unpaired reads to the file specified by --merge. Disabled by default.
  -6, --phred64                        indicate the input is using phred64 scoring (it'll be converted to phred33, so the output will still be phred33)
  -z, --compression                    compression level for gzip output (1 ~ 9). 1 is fastest, 9 is smallest, default is 4. (int [=4])
      --stdin                          input from STDIN. If the STDIN is interleaved paired-end FASTQ, please also add --interleaved_in.
      --stdout                         stream passing-filters reads to STDOUT. This option will result in interleaved FASTQ output for paired-end output. Disabled by default.
      --interleaved_in                 indicate that  is an interleaved FASTQ which contains both read1 and read2. Disabled by default.
      --reads_to_process               specify how many reads/pairs to be processed. Default 0 means process all reads. (int [=0])
      --dont_overwrite                 don't overwrite existing files. Overwritting is allowed by default.
      --fix_mgi_id                     the MGI FASTQ ID format is not compatible with many BAM operation tools, enable this option to fix it.
  -V, --verbose                        output verbose log information (i.e. when every 1M reads are processed).
  -A, --disable_adapter_trimming       adapter trimming is enabled by default. If this option is specified, adapter trimming is disabled
  -a, --adapter_sequence               the adapter for read1. For SE data, if not specified, the adapter will be auto-detected. For PE data, this is used if R1/R2 are found not overlapped. (string [=auto])

      --detect_adapter_for_pe          by default, the auto-detection for adapter is for SE data input only, turn on this option to enable it for PE data.
