[EMBOSS] fuzznuc pattern expansion

[Bernd Web]

Hi

Using fuzznuc I get illegal pattern warnings. I realize what is going on:

"You can use ambiguity codes for nucleic acid searches but not within
[] or {} as they expand to bracketed counterparts. For example, "s" is
expanded to "[GC]" therefore [S] would be expanded to [[GC]] which is
illegal."

However, what I cannot find it how to suppress this expansion. Is this
possible? We actually need to have these ambiguity remain as they are
within [] as the input sequences can contain R, Y, B, N themselves for
example. Thus, [GCS] is a pattern we actually want to be able to use.


Kind regards,
Bernd
