Why is `--alt-ali` disabled for nucleotide searches?

[romanhaa]

Hi there! I'm wondering why the --alt-ali flag is disabled in nucleotide mode.

// src/alignment/Alignment.cpp
if (altAlignment > 0) {
    if (Parameters::isEqualDbtype(querySeqType, Parameters::DBTYPE_NUCLEOTIDES)) {
        Debug(Debug::ERROR) << "Alternative alignments are not supported for nucleotides.\n";
        EXIT(EXIT_FAILURE);
    }

We'd love to use mmseqs2 but this is a blocker for us. Is it just that it's never been implemented?

Curious to hear from you!
