KentUtils are the UCSC Genome Bioinformatics Group's suite of biological analysis and web display programs as well as some of Jim Kent's own tools [1],[2],[3].

Availability and loading module

In Compute Canada we provide all these tools through the kentutils module:

[name@server ~]$ module spider kentutils/20180716

Which should give you the usual prerequisites:

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
  kentutils: kentutils/20180716
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
    Description:
      Kent utilities: collection of tools used by the UCSC genome browser.

    Properties:
      Bioinformatic libraries/apps / Logiciels de bioinformatique

    You will need to load all module(s) on any one of the lines below before the "kentutils/20180716" module is available to load.

      nixpkgs/16.09  gcc/5.4.0
      nixpkgs/16.09  gcc/6.4.0
      nixpkgs/16.09  gcc/7.3.0
      nixpkgs/16.09  intel/2016.4

      ================
       - Homepage: http://genome.cse.ucsc.edu/

To load, simply load the prerequisites before or along with the package:

[name@server ~]$ module load gcc/5.4.0 kentutils/20180716

Or

[name@server ~]$ module load gcc/6.4.0 kentutils/20180716

Or

[name@server ~]$ module load gcc/7.3.0 kentutils/20180716

Or

[name@server ~]$ module load intel/2016.4 kentutils/20180716

Or

[name@server ~]$ module load intel/2018.3 kentutils/20180716

The availability of different pre-requisites allow you to load other modules that you might need in your pipeline without affecting the KentUtils load.

Versions

The latest version of KentUtils tools in the software stack was released in April 2018 [4]

Documentation

Issuing the command without any arguments will give a brief description of the executable in most cases.

For example:

[name@server ~]$ gtfToGenePred

Will result in:

gtfToGenePred - convert a GTF file to a genePred
usage:
   gtfToGenePred gtf genePred

options:
     -genePredExt - create a extended genePred, including frame
      information and gene name
     -allErrors - skip groups with errors rather than aborting.
      Useful for getting infomation about as many errors as possible.
     -ignoreGroupsWithoutExons - skip groups contain no exons rather than
      generate an error.
     -infoOut=file - write a file with information on each transcript
     -sourcePrefix=pre - only process entries where the source name has the
      specified prefix.  May be repeated.
     -impliedStopAfterCds - implied stop codon in after CDS
     -simple    - just check column validity, not hierarchy, resulting genePred may be damaged
     -geneNameAsName2 - if specified, use gene_name for the name2 field
      instead of gene_id.
     -includeVersion - it gene_version and/or transcript_version attributes exist, include the version
      in the corresponding identifiers.

Many of the KentUtils executables are poorly documented. If you require specific help about the executables, you can submit questions to the main UCSC discussion list. See [5].
