In all our experimental validations, we compare the proposed algorithm ViSpA with the state-of-the-art tool ShoRAH as well as with ViSpA on ShoRAH-corrected reads (ShoRAHreads + ViSpA). We say the quasispecies sequence is captured if one of the candidate sequences exactly matches it. We measure the quality of assembling by portion of the real quasispecies sequences being captured by candidate sequences (sensitivity = +
