Input folder (-i example), input files in the format of .gbff.gz (-f .gbff.gz), use GbffParser.py in scripts to extract contigs and ORFs (--ot 1), provide genbank files (--g example), use Module A2 (local search, --m 2), annotate the ORFs of antibiotic and metal resistance (--a Y), use usearch (--u usearch), output folder (example/example_output), input taxonomy metadata (--tx taxon.txt) and columns for phylum to strain level (--tc 4,10)

Input folder (-i example), input files in the format of .gbff (-f .gbff), use GbffParser.py in scripts to extract contigs and ORFs (--ot 1), provide genbank files (--g example), use Module A1 (global search, --m 1), annotate the ORFs of antibiotic and metal resistance (--a Y), use diamond (--u diamond), output folder (example/example_output), input taxonomy metadata (--tx taxon.txt) and columns for phylum to strain level (--tc 4,10)

Input folder (-i example), input files in the format of .fa (-f .fa), input ORF files (--o .faa), ORFs were extracted from genbank files (--ot 1), use prodigal to predict ORFs for input sequence files with no ORF input (--prodigal prodigal), use Module A2 (local search, --m 2), annotate the ORFs of antibiotic and metal resistance (--a Y), use blast directly (--u None, time-consuming, not recommended!), output folder (example/example_output), no input taxonomy metadata (--tx None) and columns for phylum to strain level (--tc None)
python I-VIP.py -i example -f .fa --o .faa --ot 1 --a Y --m 2 --t 10 --u None --r example/example_output --tc None --tx None
Requirement: cmsearch, blast
Optional: prodigal, usearch, diamond, and cytoscape
Please download the whole package I-VIP.py, scripts and database
Please remove ":", "____", and "#" from your filename
It's highly recommended to keep less than 10,000 files in your input folder
The Integron Visualization and Identification Pipeline (I-VIP) is a well-organized pipeline to identify, classify, annotate and visualize class 1 integrons (Fig 1) in complete/draft genomes and assembled metagenomes. To facilitate flexible application by the users, I-VIP was separated into two modules; Module A for integron identification and classification (orange framework in Fig 1), and Module B for integron extraction, annotation and visualization (blue framework in Fig 1). The I-VIP also provides multiple optional parameters and diverse output formats for further analysis by the user end (more details in the following sections).
