The build must be defined for the input files and must be the same for both files.
Use the pencil icon to add the build to the files if necessary.

-----

**Dataset formats**

The SNP dataset is in interval_ format, with a column of SNPs as described below.
The gene dataset is in BED_ format with 12 columns.  The output dataset is also interval.
(`Dataset missing?`_)

.. _interval: ./static/formatHelp.html#interval
.. _BED: ./static/formatHelp.html#bed
.. _Dataset missing?: ./static/formatHelp.html

**What it does**

This tool identifies which SNPs create amino-acid changes in the specified 
coding regions.  The first input file contains the SNPs and must be an interval file.
It needs the chromosome, start, and end position as well as the SNP.  The 
SNP can be given using ambiguous-nucleotide symbols or a list of two to four
alleles 
separated by '/'.  Any other columns in the first input file will not be
used but will be kept for the output.  The second input file contains the genes
to be used for defining the coding regions.  This file must be a BED file with
the first 12 columns standard BED columns.  The output is the same as the
first input file with
several columns added: the name field from the line of the gene input file
used, the amino acids, the codon number, and the reference nucleotide that 
changed in the amino acid.
The amino acids are listed with the reference amino acid first, then a colon,
and then the amino acids for the alleles.  If a SNP is not in a coding region
or is synonymous then it is not included in the output file.

**Example**

- first input file, with SNPs::

    chr22  15660821  15660822  A/G
    chr22  15825725  15825726  G/T
    chr22  15827035  15827036  G
