Some explanations about the options


input Section
msf -- gapany [set of sequences] (-msf)
File containing a sequence alignment.
enter either the name of a file or the actual data
if you are using Netscape 2.x or later, you can select a file by typing its name, or better, by selecting it with the Netscape file browser (Browse button)
OR you can type your data in the next area, or cut and paste it from another application.
(but not both)

advanced Section
Method to use -- Multiple substitution correction methods for nucleotides (-nucmethod)
Multiple substitution correction methods for nucleotides.
Method to use -- Multiple substitution correction methods for proteins (-protmethod)
Multiple substitution correction methods for proteins.
Use the abiguous codes in the calculation. (-ambiguous)
Option to use the abiguous codes in the calculation of the Jukes-Cantor method or if the sequences are proteins.
Weight given to gaps (-gapweight)
Option to weight gaps in the uncorrected (nucleotide) and Jukes-Cantor distance methods.
Base position to analyse. (-position)
Choose base positions to analyse in each codon i.e. 123 (all bases), 12 (the first two bases), 1, 2, or 3 individual bases.
Calculate the a-parameter (-calculatea)
This will force the calculation of the a-parameter in the Jin-Nei Gamma distance calculation, otherwise the default is 1.0 (see -parametera option).
a-parameter (-parametera)
User defined a parameter to be use in the Jin-Nei Gamma distance calculation. The suggested value to be used is 1.0 [Jin et al.] and this is the default.
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,CLUSTALW
You may enter in the text area a database entry code, or an accession number, in this form:
database:entry_name
or:
database:accession.
