Dear members of the community
Perform the sequencing of 4 samples with the marker RNA16s. To build the phylogenetic tree I did it following the tutorial “Moving Pictures”, however my phylogenetic tree shows many polytomies.
Based on the above I am interested in making a condensation of my phylogenetic tree, and be able to obtain fasta sequences representative of only some bacteria genera, my question is as follows Is there any kind of tutorial to be able to extract only one group of fasta sequences, to be able to generate a condensed phylogenetic tree?
I appreciate your help, best regards
