statal - basic report with #seq

[tseemann]

Is there a way for statal to give me the basic information of

• name of the alignment (if the format supports it)
• number of entries
• length of the the alignment
• alphabet eg. AGTC AGTCN-

Perhaps this could be the default when no -sg* option is provided?

That functionality has been for long time implemented in readAl.
Available options are -format -type and -info.

[tseemann]

Those options cover most of what I asked, except for the alphabet. It does detect 'dna' in general,

% readal -type -in full.aln
## Input file datatype  nucleotides:dna

But not the actual IUPAC characters included.

Does it use N or other partial-ambiguous characters?
Does it have gaps?
Does it have any other "bad" characters like pads (*) or (X) or numbers (0-9) like Nexus often use.
