Clustalw: Multiple Alignments (Des Higgins)
Advanced clustalw form
Some explanations about the options
- Toggle Slow/Fast pairwise alignments (-quicktree)
- slow: by dynamic programming (slow but accurate)
- fast: method of Wilbur and Lipman (extremely fast but approximate)
- Sequence format
- The sequence will be automatically converted in the format needed for the program
- providing you enter a sequence either:
- in plain (raw) sequence format or in one of the following known formats:
- IG,GenBank,NBRF,EMBL,GCG,DNAStrider,Fitch,fasta,Phylip,PIR,MSF,ASN,PAUP
- You may enter in the text area a database entry code, or an accession number, in this form:
database:entry_name
or:
database:accession.
