MapSeq takes too long in file clustering

[R-Nurdiansyah]

Hi João,

I tried using MAPseq to analyze my zymo mock dataset using Greengenes2 database (downloaded here: https://greengenes2.ucsd.edu/) as a reference. After editing the database as instructed, I ran the following code:
./mapseq -fastq [my forward reads.fa] [my reverse reads.fa] [edited GG2 taxonomy database] > [result.fa.mseq] -nthreads 32
It could detect my database but then it proceed to do clustering, which took too long. The program ran for almost a week, then it was finally terminated by my HPC admin and it is not even done yet.

The following screenshot was taken after more than 48 hours running. I didn't take any screenshot after that.

Is there anything to do to resolve this issue? Or maybe I made a mistake?
Thanks in advance
