[EMBOSS] inosine in nucleotide sequence databases

[Wells, Isabelle]

Hi all,
Can emboss handle inosine in nucleotide sequences? We have a nucleotide file in embl format where some sequences contain inosine. Dbiflat doesn't seem to index the database properly although no error message was given and those inosine containing sequences cannot be retrieved with seqret. Any suggestions on what we could do apart from replacing inosine by X or N?
Many thanks,
Isabelle Wells
