## Function

Merge two overlapping feature tables

## Description

featmerge reads two feature tables for the same sequence and combines them into a single table.

## Algorithm

The second feature table is appended to the first, retaining the original order.

## Usage

This run merges the GFF format output of one of the antigenic examples with the original feature table read from SwissProt. Here is a sample session with featmerge

    % featmerge
    Merge two overlapping feature tables
    Input feature table: tsw:actb1_takru
    Second input feature table: ../antigenic-keep/actb1_takru.antigenic
    Features output [actb1_takru.gff]:

    CC   -!- FUNCTION: Actins are highly conserved proteins that are involved
    CC       in various types of cell motility and are ubiquitously expressed
    CC       in all eukaryotic cells.
    CC   -!- SUBUNIT: Polymerization of globular actin (G-actin) leads to a
    CC       structural filament (F-actin) in the form of a two-stranded helix.
    CC       Each actin can bind to 4 others.
    CC   -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton.
    CC   -!- TISSUE SPECIFICITY: Widely distributed. Not expressed in skeletal
    CC       muscle.
    CC   -!- PTM: Oxidation of Met-44 by MICALs (MICAL1, MICAL2 or MICAL3) to
    CC       form methionine sulfoxide promotes actin filament
    CC       depolymerization. Methionine sulfoxide is produced
    CC       stereospecifically, but it is not known whether the (S)-S-oxide or
    CC       the (R)-S-oxide is produced (By similarity).
    CC   -!- MISCELLANEOUS: In vertebrates 3 main groups of actin isoforms,
    CC       alpha, beta and gamma have been identified. The alpha actins are
    CC       found in muscle tissues and are a major constituent of the
    CC       contractile apparatus. The beta and gamma actins coexist in most
    CC       cell types as components of the cytoskeleton and as mediators of
    CC       internal cell motility.
    CC   -!- MISCELLANEOUS: There are three different beta-cytoplasmic actins
    CC       in Fugu rubripes.
    CC   -!- SIMILARITY: Belongs to the actin family.

## Output file format

The output is a standard EMBOSS feature file.

The results can be output in one of several styles by using the command-line qualifier `-offormat xxx`, where 'xxx' is replaced by the name of the required format. The available format names are: gff (gff3), gff2, embl (em), genbank (gb, refseq), ddbj, refseqp, pir (nbrf), swissprot (swiss, sw), dasgff and debug.

See: http://emboss.sf.net/docs/themes/FeatureFormats.html for further information on feature formats.

featmerge writes a single feature table. By default the output is in 'gff' feature format.
