SINA alignment action/method does not exist in Qiime2. Could you please introduce another way to do that in Qiime2?
The qiime 2 plugin
fragment-insertion can be used to make trees:
Is this what you wanted to do with SINA?
Let me give you an example. I was reading a paper written ‘Sequences shorter than 300 nucleotides orlonger than 600 nucleotides were also discarded. The unique se-quences were then aligned in mothur by default setting with referring to the pre-aligned mcr Asequences provided by the Fun-gene Pipeline database’.
I do not need to draw a phylogeny tree. I want only align my sequences with a reference sequences. I found this message in Qiime2 forum:
I am looking for a plugin/action/ method or tool in Qiime2 to align my sequences (query) with reference sequences. By the way, there is an alignemt option in Qiime2, Maff, but its function is de-novo. it does not align the query on the reference sequences.
Now, can you help me with this details I gave to you?
Yes, thank you for providing me with those details.
The method you cited mentions mothur:
unique se-quences were then aligned in mothur
mothur uses a reference msa when building feature, and some Qiime 2 plugins like dada2 do not need a reference at all.
If you want to use SINA, that community tutorial is a good place to start. MAFFT now supports ref based alignments, but those features are not available in the Qiime 2 plugin yet.
I have another question for you, if you are interested in answering.
The only time I do MSA is when want a phylogeny tree for UniFrac distances or graphs. Why do you want to do MSA?
