  2. Unpack Distribution

    The "RepeatMasker" directory will be made in the current working directory. [username@sc090 ~]$ tar xvzf RepeatMasker-open-3-3-0-p1.tar.gz
    RepeatMasker/
    RepeatMasker/ArrayList.pm
    RepeatMasker/RepbaseRecord.pm
    ...
    RepeatMasker/ArrayListIterator.pm
    RepeatMasker/ProcessRepeats
    RepeatMasker/DeCypherSearchEngine.pm

  3. Get the RepeatMasker Library (Repbase)

    To get the library (repeatmaskerlibraries-20120418.tar.gz) you need to register at the GIRI's website. After getting the library, then locate the distribution into the "RepeatMasker" directory.

  4. Unpack Distribution
    [username@sc090 ~]$ cd ./RepeatMasker/
    [username@sc090 RepeatMasker]$ tar xvzf repeatmaskerlibraries-20120418.tar.gz
    Libraries/
    Libraries/README.html
    Libraries/README
    Libraries/RepeatMaskerLib.embl
    [username@sc090 RepeatMasker]$ rm repeatmaskerlibraries-20120418.tar.gz
    rm: remove regular file `repeatmaskerlibraries-20120418.tar.gz'? y

  5. Confirm Perl installation path

    [username@sc090 RepeatMasker]$ which perl
    /usr/local/bin/perl

  6. Run configure script

    The RepeatMasker will be installed into ~/RepeatMasker/. [username@sc090 RepeatMasker]$ perl ./configure
    RepeatMasker Configuration Program

    This program assists with the configuration of the
    RepeatMasker program. The next set of screens will ask
    you to enter information pertaining to your system
    configuration. At the end of the program your RepeatMasker
    installation will be ready to use.

    <PRESS ENTER TO CONTINUE>
    # Press Enter

    **PERL INSTALLATION PATH**

      This is the full path to the Perl interpreter.
      e.g. /usr/local/bin/perl or enter "env" if you prefer to use
      the "/usr/bin/env perl" mechanism to locate perl.

    Enter path [ /usr/local/bin/perl ]: # Press Enter

    **REPEATMASKER INSTALLATION PATH**

      This is the path to the location where
      the RepeatMasker program has been installed.

    Enter path [ /home/username/RepeatMasker ]: # Press Enter

      -- Building monolithic RM database...

    **TRF INSTALLATION PATH**

      This is the path to the location where
      the TRF program can be found. This is used by the RepeatProteinMask program. [NOTE: This script assumes the trf program is called "trf". If it is name trf###-linux.exe you will need to create a symlink called "trf" to it or rename it first.

    Enter path [ ]: /usr/local/bin

    Add a Search Engine:
       1. CrossMatch: [ Un-configured ]
       2. RMBlast - NCBI Blast with RepeatMasker extensions: [ Un-configured ]
       3. WUBlast/ABBlast (required by DupMasker): [ Un-configured ]
       4. DeCypher (TimeLogic): [ Un-configured ]

       5. Done

    Enter Selection: 2

    **RMBlast (rmblastn) INSTALLATION PATH**

      This is the path to the location where
      the rmblastn and makeblastdb programs can be found.

    Enter path [ ]: /usr/local/package/blast+/2.2.27/bin

    Building RMBlast frozen libraries..

    Do you want RMBlast to be your default
    search engine for Repeatmasker? (Y/N) [ Y ]: # Press Enter

    Add a Search Engine:
       1. CrossMatch: [ Un-configured ]
       2. RMBlast - NCBI Blast with RepeatMasker extensions: [ Configured, Default ]
       3. WUBlast/ABBlast (required by DupMasker): [ Un-configured ]
       4. DeCypher (TimeLogic): [ Un-configured ]

       5. Done

    Enter Selection: 5

      -- Setting perl interpreter...

    Congratulations! RepeatMasker is now ready to use.
    The program is installed with a minimal repeat library
    by default. This library only contains simple, low-complexity,
    and common artefact ( contaminate ) sequences. These are
    adequate for use with your own custom repeat library. If you
    plan to search using common species specific repeats you will
    need to obtain the complete RepeatMasker repeat library from
    GIRI ( www.giriinst.org ) and install it in /home/username/RepeatMasker.

    Further documentation on the program may be found here:
      /home/username/RepeatMasker/repeatmasker.help
