There is a general principle that the output sequence type matches the
input unless explicitly stated (transeq for example).

This is so that wrappers, GUIs, etc. know what output sequence type to

You can try to specify gapany as the output sequence type. I think this
will fix your modified ACD file (I'm away from EBI until next week and
will look more closely then).
