Re: [Seqan-dev] i am lost again

The offending line is:

> std::ifstream fasta(options.inFile,
> std::ios_base::in | std::ios_base::binary);

The ifstream from the STL does not know about SeqAn Strings (which is the type of options.inFile).

Try this instead:

std::ifstream fasta(toCString(options.inFile), std::ios_base::in | std::ios_base::binary);
