The error message doesn't help but the only thing in a TranscriptDb
object that can be modified is the seqlevels. Since TranscriptDb
objects are essentially read-only, this is achieved by storing the
user-supplied seqlevels in a slot. Supporting user-supplied seqlengths,
circularity flags and genome is doable but would require modifying the
definition of the TranscriptDb class first. I'm adding this to our
list.

BTW, everybody seems to be using TxDb as an abbreviation for
TranscriptDb these days. I guess this is because we also have
the TxDb.* packages which are just TranscriptDb objects wrapped
into packages. So I guess it's time to rename the TranscriptDb
class -> TxDb.

Cheers,
H.
