merger |
Please help by correcting and extending the Wiki pages.
merger reads two overlapping input sequences of the same type (typically nucleotide) and uses a global alignment algorithm (Needleman & Wunsch) to optimally align the sequences. A merged sequence is generated from the alignment and writen to the output file. The sequence alignment is also written.
It uses a global alignment algorithm (Needleman & Wunsch) to optimally align the sequences and then creates a merged sequence from the alignment. When there is a mismatch in the alignment between the two sequences, the base included in the merged sequence is the base from the sequence which has the best local sequence quality score.
The following heuristic is used to find the sequence quality score. If one of the bases is a 'N', then the other sequence's base is used. Otherwise, a window size around the disputed base is used to find the local quality score. This window size is increased from 5, to 10 to 20 bases or until there is a clear decision on the best choice. If there is no best choice after using a window of 20, then the base in the first sequence is used.
To calculate the quality of a window of a sequence around a base:
* quality = sequence value/length under window either side of the base
* sequence value = sum of points in that window
* unambiguous bases (ACGTU) score 2 points
* ambiguous bases (MRWSYKVHDB) score 1 point
* Ns score 0 points
* off end of the sequence scores 0 points
This heavily discriminates against the iffy bits at the end of sequence reads.

Typically, one of the sequences will need to be reverse-complemented to put it into the correct orientation to make it join. For example:
% merger file1.seq file2.seq -sreverse2 -outseq merged.seq

The output is a standard EMBOSS alignment file.
The results can be output in one of several styles by using the command-line qualifier -aformat xxx, where 'xxx' is replaced by the name of the required format. Some of the alignment formats can cope with an unlimited number of sequences, while others are only for pairs of sequences.
The available multiple alignment format names are: unknown, multiple, simple, fasta, msf, trace, srs
The available pairwise alignment format names are: pair, markx0, markx1, markx2, markx3, markx10, srspair, score
See: http://emboss.sf.net/docs/themes/AlignFormats.html for further information on alignment formats.
The output report file contains descriptions of the positions where there is a mismatch in the alignment and shows the alignment. Where there is a mismatch in the alignment, the chosen base is written in uppercase.

This program was originally written to aid in the reconstruction of mRNA sequences which had been sequenced from both ends as a 5' and 3' EST (cDNA). eg. joining two reads produced by primer walking sequencing.
The gap open and gap extension penalties have been set at a higher level than is usual (50 and 5). This was experimentally determined to give the best results with a set of poor quality EST test sequences.
Care should be taken to reverse one of the sequences (e.g. using the qualifier -sreverse2) if this is required to get them both in the correct orientation..
merger uses the memory-hungry Needleman & Wunsch alignment. The required memory may be greater than the available memory when attempting to merge large (cosmid-sized or greater) sequences.
| Program name | Description |
|---|---|
| cons | Create a consensus sequence from a multiple alignment |
| consambig | Create an ambiguous consensus sequence from a multiple alignment |
| megamerger | Merge two large overlapping DNA sequences |
