Function
</H2>
Align nucleic coding regions given the aligned proteins
<H2>
Description
</H2>
<b>tranalign</b> is a re-implementation in EMBOSS of the program
<b>mrtrans</b> by Bill Pearson.
<p>
<b>tranalign</b> is a simple program that allows you to produce aligned
cDNA sequences from aligned protein sequences. This can be very useful
for phylogeny programs, e.g. in PHYLIP - dnadist, dnapars, dnaml, etc.
In general, it is better to use protein sequences for multiple
alignments, but to use DNA sequences for phylogeny. This can be time
consuming when there are gaps in the aligned protein sequences.
<p>
<b>tranalign</b> takes a set of (unaligned) nucleic sequences and a set of
<i>aligned</i> protein sequences. It reads the first nucleic sequence
and the first protein sequence, translates the nucleic sequence in each of the
three forward frames, compares the protein sequence to the translated nucleic
sequence to find the protein coding region, and then writes out the nucleic
sequence that encoded the protein.
<p>
The sequences must be in the same order in both sets of sequences. A
common problem you should be aware of is that some alignment program
(including clustalw/<b>emma</b>) will re-order the aligned sequences to
group similar sequences together.
<p>
The protein library may include '-' characters to specify alignments.
Each '-' character in the protein library is ignored during the sequence
comparison but replaced by '---' in the nucleic sequence output to form the aligned nucleic sequences.
<p>
<b>tranalign</b> finds the coding regions for contiguous sequences only.
It will not splice together different exons to produce a coding
sequence. You should therefore use either mRNA sequences, or nucleic
sequences which you have constructed to hold a contiguous coding region
(maybe using <b>extractseq</b> or <b>yank</b> and <b>union</b>?).
<H2>

Input file format
</H2>
The input is a set of unaligned nucleic sequences and the set of aligned
protein sequences to be used as a guide in the alignment of the output
nucleic sequences.
<p>
The ID names of the nucleic acid and protein sequences are NOT checked
to see if they correspond to each other. They can have any names.
<p>
There must be at least as many protein sequences as nucleic acid
sequence - extra protein sequences are ignored.
<p>
Each of the nucleic acid sequences must have a corresponding protein
sequence which is derived from the coding region of that nucleic acid
sequence. The two sets of sequences must be in the same order.

<p>
The output is the regions of the nucleic acid sequences which code for
the corresponding protein sequence, with gap characters ('-') introduced
so that they have the same alignment as the corresponding protein
sequences.
<H2>
Data files
</H2>
None.
<H2>
Notes
</H2>
The sequences must be in the same order in both sets of sequences. A
common problem you should be aware of is that some alignment program
(including clustalw/<b>emma</b>) will re-order the aligned sequences to
group similar sequences together.
<H2>
References
</H2>
None.
<H2>
Warnings
</H2>
None.
<H2>
Diagnostic Error Messages
</H2>
"No guide protein sequence available for nucleic sequence xxx" - the
corresponding protein sequence for this nucleic sequence has not been
input. You have input more nucleic acid sequences than protein sequences.
<p>
"Guide protein sequence xxx not found in nucleic sequence xxx" - the
region of the nucleic sequence which codes for the protein was not
found. The coding region in the nucleic acid sequence must be a single
contiguous sequence. The protein sequence might not be the
corresponding one for this nucleic acid sequence if they are out of
order.
<H2>
Exit status
</H2>
It always exits with status 0.
<H2>
Known bugs
</H2>
None.
