I got a reply from the EBI support team saying that the webserver they
provide is outdated, when compared to the versions of NEEDLE we (me on the
web and Peter on his local machine) used. So, BioPython is nice and
up-to-date, it's their server that is quite outdated.
" Actually the WSEmboss web service uses an older version of EMBOSS (2.9.0),
exibits this behaviour. I suggest you contact the BioPython folks and let
know that older versions of EMBOSS behave differently.
If you want to use the latest version of EMBOSS I suggest looking at using
Soaplab services (see
All the best,
Support at EBI"
