Ancestral sequence determination

Please indicate who you are:

Please select the alignment format, and enter the alignment:

FASTA

PAUP
PHYLIP
YAMA

or provide the (Unix - full path) file name for the alignment:

or select one of the pre-formatted alignments from the list:

Please enter the name of the sequence to provide the range:

Please enter the range in the above sequence for evaluating the alignment - from: to

For the description of how to describe a phylogenetic tree, please see help.

Please describe the relationship between the species in the alignment:

Please indicate the scoring method for nucleotide substitution:

anchor on number of active sequences
anchor on non-gap active sequences count
anchor independent on active sequences

Please indicate the maximal number of substitutions along the tree (anchor modifier): .

Minimal region length should be: in at least: active sequences.

The gaps should be treated as:

breaking any ancestral sequence
any other character in the alignment
wildcard - not propagated

Please indicate the result output:
