[Bioperl-l] How to store results of searches of translated DNA in SeqFeature::Store database of the original DNA?

[Doug]

One more note: I did try using PositionProxy but it failed. It doesn't
implement seq_id() and so can't be stored in the DB:

------------- EXCEPTION: Bio::Root::NotImplemented -------------
MSG: Abstract method "Bio::SeqFeatureI::seq_id" is not implemented by
package Bio::SeqFeature::PositionProxy.
This is not your fault - author of Bio::SeqFeature::PositionProxy
should be blamed!
