Exon Mapping

Hi,

I'm looking for an elegant (failing that, feasable) method to map
genomic sequences to
protein sequences. The net result should look something like this:

Genomic: -------++++++-----------+++++++++++-----++++++
Protein:        ******           ***********     ******



Where the "+" are exon codons, "-" intron codons, and "*" amino-acids.

Naturally, the data can appear as a mapping table, or anything else
which is parseable.

Given protein sequence (e.g. from SwissProt), how do I:

1) Trace the genomic sequence? Problem: usually I cannot find it, rather
I come up with a cDNA. I do not actually need the intron information,
but I do need to know where an exon begins and ends on the cDNA
sequence.

2) Map the above information automatically to my protein sequence.

I have GCG v9.0, and WWW access. My platform is a Silicon-Graphics Indy.

Any comment would be useful.

Many thanks,

Iddo
