InterPro is a database which integrates together predictive information about proteins’ function from a number of partner resources, giving an overview of the families that a protein belongs to and the domains and sites it contains.

Basic functions of this tool

  • removes special characters from FASTA sequences
  • splits FASTA into groups of 1000 sequences
  • runs InterProScan with user-specified options on each of the 1000-sequence files in parallel
  • re-combines output files from all groups of 1000
  • parses the XML output from InterProScan to generate a gene association file (GAF) (and several other files)

Results and analysis from the application of InterProScan annotation to the Official gene set v3.0 protein set from Diaphorina citri followed by a differential expression analysis was presented at a seminar in the University of Arizona Animal and Comparative Biomedical Sciences in Fall 2020. The slides and video are available online.


This tool accepts a peptide FASTA file. For those users with nucloetide sequences some documentation has been provided for using TransDecoder (although other tools are also acceptable). The TransDecoder app is available through CyVerse or as a BioContainer for use on the command line.


As both GOanna and InterProScan provide GO annotations, their outputs are provided in GAF format. The ‘Combine GAFs’ tool can then be used to make a single GAF of GO annotations, if desired.

Getting the InterProScan Data

Partner data are available from the InterProScan FTP site. These data are available as two separate downloads and can be obtained following these instructions:

1. Partner Data excluding Panther

md5sum -c
tar -pxvzf interproscan-data-5.41-78.0.tar.gz

tar options

  • p = preserve the file permissions
  • x = extract files from an archive
  • v = verbosely list the files processed
  • z = filter the archive through gzip
  • f = use archive file

2. Getting the Panther data

cd interproscan-5.36-75.0/data
md5sum -c panther-data-14.1.tar.gz.md5
tar -pxvzf panther-data-14.1.tar.gz

These data will be unarchived into this directory structure. They will need to be mounted to the container at run time.


Help and Usage Statement

                                           is not set, ALL analyses will be run.

-b <OUTPUT-FILE-BASE>                     Optional, base output filename (relative or absolute path).
                                           Note that this option, the output directory (-d) option and
                                           the output file name (-o) option are mutually exclusive.  The
                                           appropriate file extension for the output format(s) will be
                                           appended automatically. By default the input file
                                           path/name will be used.

-d <OUTPUT-DIR>                            Optional, output directory. Note that this option, the

                                           are mutually exclusive. The output filename(s) are the
                                           same as the input filename, with the appropriate file
                                           extension(s) for the output format(s) appended automatically .
