[EMBOSS] distmat Uncorrected distance > 100

[Sumit Middha]

Hi,

I tried using distmat from emboss on some alignments and am getting 
scores in excess of 100 (using all default options).

I am not sure how scores can exceed 100.

D = uncorrected distance = p-distance = 1-S
where S = m/(npos + gaps*gap_penalty)  

So D is like a percentage and equals number of substitutions per 100 bases or amino acids.

Please correct me or point me to an explanation which will help clarify my doubt.

Thanks,
Sumit
