[EMBOSS] Question about make use of multiple fields indexing by dbxfasta or dbxflat

[Jon Ison]

Hi Jean

The short answer is, by adding extra fields, all programs that
read sequence(s) would benefit from increased flexibility in
how sequences may be specified on the command-line.

You can read about how to specify sequences using the Uniform
Sequence Address (USA) model here:
http://emboss.sourceforge.net/docs/themes/UniformSequenceAddress.html

(look under "The Full USA syntax")

If any applications absolutely required certain indexing then that
would be mentioned in the application documentation, accessible via:
http://emboss.sourceforge.net/apps/

Cheers

Jon
