**What it does**

This tool predicts open reading frames (orfs) from a given DNA Sequence. That tool is not knowlegde-based.

The recommended way is to use a trained Glimmer3 with ICM model. Use the knowlegde-based version for that and insert/generate a training set.

**Example**

Suppose you have the following DNA sequences::

    >SQ   Sequence 8667507 BP; 1203558 A; 3121252 C; 3129638 G; 1213059 T; 0 other;
    cccgcggagcgggtaccacatcgctgcgcgatgtgcgagcgaacacccgggctgcgcccg
    ggtgttgcgctcccgctccgcgggagcgctggcgggacgctgcgcgtcccgctcaccaag
    cccgcttcgcgggcttggtgacgctccgtccgctgcgcttccggagttgcggggcttcgc
    cccgctaaccctgggcctcgcttcgctccgccttgggcctgcggcgggtccgctgcgctc
    ccccgcctcaagggcccttccggctgcgcctccaggacccaaccgcttgcgcgggcctgg
    .......

Running this tool will produce a FASTA file with predicted genes and glimmer output files like the following::

    >SQ   Sequence 8667507 BP; 1203558 A; 3121252 C; 3129638 G; 1213059 T; 0 other;
