usage: quantpi init [-h] [-d WORKDIR] [--check-samples] [-s SAMPLES] [-b {simulate,trimming,rmhost,profiling}] [--trimmer {oas1,sickle,fastp}] [--rmhoster {bwa,bowtie2,minimap2,kraken2,kneaddata}]

options:
  -h, --help            show this help message and exit
  -d, --workdir WORKDIR
                        project workdir (default: ./)
  --check-samples       check samples, default: False

                        desired input:
                        samples list, tsv format required.

                        if begin from trimming, rmhost, or assembly:
                            if it is fastq:
                                the header is: [sample_id, fq1, fq2]

                                the header is: [sample_id, sra]

                        if begin from simulate:
                                the header is: [id, genome, abundance, reads_num, model]

Real world

Step 1: download LMAS data

A set of simulated samples were generated from the genomes in the ZymoBIOMICS standard though the InSilicoSeq sequence simulator (version 1.5.2), including both even and logarithmic distribution, with and without Illumina error model. The number of read pairs generated matches the number of read pairs in the real data for each distribution. The following samples are available in Zenodo:

  • ENN - Evenly distributed sample with no error model
  • EMS - Evenly distributed sample with Illumina MiSeq error model
  • LNN - Log distributed sample with no error model
  • LHS - Log distributed sample with Illumina HiSeq error model
➤ mkdir -p test
➤ mkdir -p test/fastq
➤ cd test
#  - mock even distributed data no error
➤ wget -c https://zenodo.org/record/5579145/files/ENN_1.fq.gz -P ./fastq/
➤ wget -c https://zenodo.org/record/5579145/files/ENN_2.fq.gz -P ./fastq/

#  - mock even distributed data illumina miseq error
➤ wget -c https://zenodo.org/record/5579145/files/EMS_1.fq.gz -P ./fastq/
➤ wget -c https://zenodo.org/record/5579145/files/EMS_2.fq.gz -P ./fastq/

#  - mock log distributed data no error
➤ wget -c https://zenodo.org/record/5579145/files/LNN_1.fq.gz -P ./fastq/
➤ wget -c https://zenodo.org/record/5579145/files/LNN_2.fq.gz -P ./fastq/

#  - mock log distributed data illumina hiseq error
➤ wget -c https://zenodo.org/record/5579145/files/LHS_1.fq.gz -P ./fastq/
➤ wget -c https://zenodo.org/record/5579145/files/LHS_2.fq.gz -P ./fastq/

Step 2: prepare samples sheet

➤ fd -a fq.gz fastq/ | sort | uniq | paste - - | awk -F'[/_]' 'BEGIN{print "sample_id\tfq1\tfq2"};{print $(NF-1) "\t" $0}' > samples.tsv 

samples.tsv looks like below:

sample_id fq1 fq2
ENN /full/path/to/ENN_1.fq.gz /full/path/to/ENN_2.fq.gz
EMS /full/path/to/EMS_1.fq.gz /full/path/to/EMS_2.fq.gz
LNN /full/path/to/LNN_1.fq.gz /full/path/to/LNN_2.fq.gz
LHS /full/path/to/LHS_1.fq.gz /full/path/to/LHS_2.fq.gz

Step 3: Init

➤ quantpi init -d . -s samples.tsv
# or
➤ python /path/to/quantpi/run_quantpi.py init -d . -s samples.tsv

Step 4: workflow list

➤ quantpi profiling_wf --list
# or
