Why do you want to use needle instead of needleall?

needleall reads two sets of sequences (many to many)

needle reads a single sequence, and a set of sequences to compare to 
(one to many).

That should be the only diufference between the applications.

The identity is in the header above each sequence alignment in the 
default output.

There are other alignment output formats available with the -aformat option.

Can you give an example of what you would like to see. We probably 
already have a format in needle and needleall that gives what you need.
