Ummmm, adaptors are not the problem, these are masked by the Roche software (well, 99.9% of the time). What's important are the paired-end linkers, and Titanium uses _two_ of them (GS20 and FLX protocols used only one). Can you please try the following: download 'sff_extract' in http://www.chevreux.org/tmp/mira_3rdparty_10-12-2009.tar.bz2 Then follow the walkthrough "Extracting paired-end data from SFF" in the 454 usage manual of MIRA (currently it's http://mira-assembler.sourceforge.net/docs/mira_454.html#section_28 Can you then please report back whether this fixes your problem?
