Aligns multiple sequence alignments (MSAs) supplied with ClustalW.
ClustalW is a general-purpose multiple sequence alignment program for DNA or proteins. Visit http://www.clustal.org/ to learn more about it.
Clustal is used as an external tool from UGENE and it must be installed on your system. To learn more about the external tools, please, read the main UGENE User Manual.
Element type: clustalw
Parameters
Parameter | Description | Default value | Parameter in Workflow File | Type |
---|---|---|---|---|
Weight matrix | For proteins, it is a scoring table which describes the similarity of each amino acid to each other. For DNA it is the scores assigned to matches and mismatches. | default | matrix | numeric Available values are:
|
End gaps | The penalty for closing a gap. | False | close-gap-penalty | boolean |
Gap distance | The gap separation penalty. Tries to decrease the chances of gaps being too close to each other. | 4.42 | gap-distance | numeric |
Gap extension penalty | The penalty for extending a gap. | 8.52 | gap-ext-penalty | numeric |
Gap open penalty | The penalty for opening a gap. | 53.90 | gap-open-penalty | numeric |
Hydrophilic gaps off | Hydrophilic gap penalties are used to increase the chances of a gap within a run (5 or more residues) of hydrophilic amino acids. | False | no-hydrophilic-gaps | boolean |
Residue-specific gaps off | Residue-specific penalties are amino specific gap penalties that reduce or increase the gap opening penalties at each position in the alignment. | False | no-residue-specific-gaps | boolean |
Iteration type | Alignment improvement iteration type. | None | iteration-type | numeric Available values are:
|
Number of iterations | The maximum number of iterations to perform. | 3 | iterations-max-num | numeric |
Tool path (required) | Path to the ClustalW tool. The default path can be set in the UGENE Application Settings. | default | path | string |
Temporary directory | Directory to store temporary files. | default | temp-dir | string |
