I am trying to analyse “Novaseq” data of marine diatom. First, I need to align my sequences to a reference database using MOTHUR. However, I could not find the reference database file (alignment file) of diatom sequences. Basically I am looking for the alignment file (fasta), template file (fasta) and the taxonomy file (tax) as required for running the align.seqs and classify.seqs commands. Please suggest how to proceed with MOTHUR analysis of my diatom rbcL sequences or if someone could share these files with me.
Thanks
