Hi all, I am trying to adapt SeqAn2 in my program. I have a problem to find out class definitions in SeqAn2. For example, in the following tutorial, https://seqan.readthedocs.io/en/master/Tutorial/InputOutput/SamAndBamIO.html#accessing-the-header `TBamContext` is used to define a variable for header information, and I want to extract the reference names (such as chr1, chr2, xxx) from it, and save them as std::string in native C++. However, the class's definition is not clear, and the interfaces for the conversion are not directly available either. Can you help point out documentation about these class type definitions in SeqAn2? Thank you. Best regards, Jin
