Dear all, I just wanted to let you know that in our preparations of the 1.4 release, we are doing some renaming for better consistency. Since the functionality is not present in the 1.3 release, you will not read about them in the 1.4 changelog. BamAlignmentRecord::rId => BamAlignmentRecord::rID BamAlignmentRecord::pos => BamAlignmentRecord::beginPos GffRecord::seqIdx => GffRecord::rID GffRecord::seqID => GffRecord::ref Also see [1]. Furthermore: RecordReader<TString, SinglePass<Mapped> > => RecordReader<TString, SinglePass<StringReader> > RecordReader<TString, DoublePass<Mapped> > => RecordReader<TString, DoublePass<StringReader> > We're sorry for all caused inconveniences. Cheers, Manuel [1] https://trac.seqan.de/ticket/1006
