sidle tutorial missing aligned sequence file

Hi again!
I think my question is also useful in this post, because it is related to another database. So that is the reason why I am posting this here and do not in a new post.

I would love to reproduce the last step of sidle documentation's Phylogenetic Tree Reconstruction. However I could not find the rep_set_aligned folder in NCBI 16S database or neither the SEPP references file. That’s the crux of the matter.

I have found some post as:

But didn't find a solution.

Maybe I need to merge-seqs? What approximation could I use?

Any help would be appreciated!! :slight_smile:

Thank you so much!
