Simple bacterial assembly and annotation pipeline
Define where the pipeline should find input data and save output data.
Path to tab-separated sample sheet
string
Path to sample sheet, either tab-separated (.tsv), comma-separated (.csv), or in YAML format (.yml/.yaml), that points to compressed fastq files.
The sample sheet must have six tab-separated columns/entries with the following headers:
ID
(required): Unique sample IDs, must start with a letter, and can only contain letters, numbers or underscoresR1
(optional): Paths to (forward) reads zipped FastQ filesR2
(optional): Paths to reverse reads zipped FastQ files, required if the data is paired-endLongFastQ
(optional): Paths to long reads zipped FastQ filesFast5
(optional): Paths to the directory containing FAST5 filesGenomeSize
(optional): A number (including decimals) ending with 'm', representing genome size.
Please be aware that files will be required based on the chosen assembly type specified with the '--assembly_type' option, which can be set to one of the following values: ['short', 'long', 'hybrid'].`
The output directory where the results will be saved. You have to use absolute paths to storage on Cloud infrastructure.
string
Email address for completion summary.
string
^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$
Set this parameter to your e-mail address to get a summary e-mail with details of the run sent to you when the workflow exits. If set in your user config file (~/.nextflow/config
) then you don't need to specify this on the command line for every run.
Parameters for QC and trim short-reads
save trimmed files
boolean
save files that failed to pass trimming thresholds ending in *.fail.fastq.gz
boolean
Skip FastQC
boolean
Skip FastP
boolean
Path to Kraken2 database.
string
See Kraken2 homepage for download
links. Minikraken2 8GB is a reasonable choice, since we run Kraken here mainly just to check for
sample purity.
Path to the Kmerfinder bacteria database (ie: '/path_to/kmerfinder/bacteria/ or '/path_to/kmerfinder/bacteria.tar.gz'). Only taxonomic group 'bacteria' is allowed. See database installation (guidelines)[https://bitbucket.org/genomicepidemiology/kmerfinder_db/src/master/] for details. The latest version can be downloaded from the KmerFinder Database FTP site or directly during pipeline execution with. Example:
--kmerfinder_db 'ftp://ftp.cbs.dtu.dk/public/CGE/databases/KmerFinder/version/latest/bacteria.tar.gz'
(Note: Downloading the KmerFinder database (~30GB) via FTP can be time-consuming. It's recommended to pre-download the database and provide the *.tar.gz file using this parameter instead of URL site.).
An older version is available on (Zenodo)[https://zenodo.org/records/13447056/files/20190108_kmerfinder_stable_dirs.tar.gz].
string
Reference FASTA file.
string
Reference GFF file.
string
Master file (*.txt) containing a summary of assemblies available in GeneBank or RefSeq. See: https://ftp.ncbi.nlm.nih.gov/genomes/ASSEMBLY_REPORTS/assembly_summary_refseq.txt
string
Parameters for the assembly
The assembler to use for assembly. Use the appropriate assembler according to the chosen assembly_type. Refer to the README.md for further clarification.
string
Which type of assembly to perform.
string
This adjusts the type of assembly done with the input data and can be any of long
, short
or hybrid
.
Extra arguments for Unicycler
string
This advanced option allows you to pass extra arguments to Unicycler (e.g. "--mode conservative"
or "--no_correct"
). For this to work you need to quote the arguments and add at least one space.
Allowed technologies for long read assembly.
string
This can be used to supply extra options to the Canu assembler. Will be ignored when other assemblers are used.
string
Extra arguments for Dragonflye
string
This advanced option allows you to add extra arguments to Dragonflye (e.g.: "--gsize 2.4m"
). For those arguments with no values/options associated (e.g.: "--nopolish"
or "--nofilter"
...) you need to add an extra space at the begining of the input string to params.dragonflye_args. Example: --params.dragonflye_args ' --nopolish'
Which assembly polishing method to use.
string
Can be used to define which polishing method is used by default for long reads.
Parameters for the annotation
The annotation method to annotate the final assembly.
string
Extra arguments for prokka annotation tool.
string
This advanced option allows you to pass extra arguments to Prokka (e.g. " --rfam"
or " --genus name"
). For this to work you need to quote the arguments and add at least one space between the arguments. Example:
--prokka_args `--rfam --genus Escherichia Coli`
Path to Bakta database
string
Download Bakta database
boolean
Specifies a configuration file for the DFAST annotation method.
string
assets/test_config_dfast.py
If you want to know how to create your config file, please refer to the DFAST readme on how to create one. The default config (assets/test_config_dfast.py
) is just included for testing, so if you want to annotate using DFAST, you have to create a config!
Skip running Kraken2 classifier on reads.
boolean
Skip annotating the assembly with Prokka /DFAST.
boolean
Skip running PycoQC
on long read input.
boolean
Skip polishing the long-read assembly with fast5 input. Will not affect short/hybrid assemblies.
boolean
Skip MultiQC
boolean
Parameters used to describe centralised config profiles. These should not be edited.
Git commit id for Institutional configs.
string
master
Base directory for Institutional configs.
string
https://raw.githubusercontent.com/nf-core/configs/master
If you're running offline, Nextflow will not be able to fetch the institutional config files from the internet. If you don't need them, then this is not a problem. If you do need them, you should download the files from the repo and tell Nextflow where to find them with this parameter.
Institutional config name.
string
Institutional config description.
string
Institutional config contact information.
string
Institutional config URL link.
string
Less common options for the pipeline, typically set in a config file.
Display help text.
boolean
Display version and exit.
boolean
Method used to save pipeline results to output directory.
string
The Nextflow publishDir
option specifies which intermediate files should be saved to the output directory. This option tells the pipeline what method should be used to move these files. See Nextflow docs for details.
MultiQC report title. Printed as page header, used for filename if not otherwise specified.
string
Email address for completion summary, only when pipeline fails.
string
^([a-zA-Z0-9_\-\.]+)@([a-zA-Z0-9_\-\.]+)\.([a-zA-Z]{2,5})$
