Short Description
A web wrapper for GeneValidator (identify problems with predicted genes)
Full Description



This is a online web application for GeneValidator. This app is currently hosted at:

GeneValidator helps in identifing problems with gene predictions and provides useful information extracted from analysing orthologs in BLAST databases. The results produced can be used by biocurators and researchers who need accurate gene predictions.

If you use GeneValidator in your work, please cite us as follows:

Dragan M<sup>‡</sup>, Moghul MI<sup>‡</sup>, Priyam A, Bustos C & Wurm Y. 2016. GeneValidator: identify problems with protein-coding gene predictions. <em>Bioinformatics</em>, doi: 10.1093/bioinformatics/btw015.



Installation Requirements

  • Ruby (>= 2.0.0)
  • NCBI BLAST+ (>= 2.2.30+) (download here).
  • MAFFT installation (>=7.273) (download here).

Please see here for more help with installing the prerequisites.


Simply run the following command in the terminal.

gem install genevalidatorapp

If that doesn't work, try sudo gem install genevalidatorapp instead.

Running From Source (Not Recommended)

It is also possible to run from source. However, this is not recommended.

# Clone the repository.
git clone

# Move into GeneValidatorApp source directory.
cd GeneValidatorApp

# Install bundler
gem install bundler

# Use bundler to install dependencies
bundle install

# Optional: run tests and build the gem from source
bundle exec rake

# Run GeneValidator.
bundle exec genevalidatorapp -h
# note that `bundle exec` executes GeneValidatorApp in the context of the bundle

# Alternativaly, install GeneValidatorApp as a gem
bundle exec rake install
genevalidatorapp -h

Launch GeneValidator

To configure and launch GeneValidatorApp, run the following from a command line.


GeneValidatorApp will automatically guide you through an interactive setup process to help locate BLAST+ binaries and ask for the location of BLAST+ databases.

That's it! Open http://localhost:4567/ and start using GeneValidator!

Advanced Usage

See $ genevalidatorapp -h for more information on all the options available when running GeneValidatorApp.
