Hi, I got the rooted.tree from qiime2, but it is a qza file. May I know how to change it into a qzv file, which can be visualized. OR change the qza file into a fasta file, which I can know the reads and draw a tree? Because all the qza file is not readable. Thanks so much.

Hi @Lu_Yang ! Unfortunately we don't have any tree-viewing visualizations at this moment, but you can export your tree artifact and load that file up into the viewer of your choice! :christmas_tree: :deciduous_tree: :evergreen_tree: :palm_tree: Let us know how it goes for you! Thanks! :t_rex:

Hi, @thermokarst , Thanks for your reply. Got that! Looking forward to qiime2's visualization of the tree. Haha ~:grin::crazy_face::blush::star_struck:

Hi, thermokarst I understand that Qimme2 cannot visualize rooted-tree.qza. So, I exported the rooted-tree.qza into a tree.nwk, which can be visualised as a tree. Obviously, this tree is built based on the rep sequences. So, instead of my Sample ID, hashed code for each rep sequence is present on t…

Hi, @zejunyan , I had the same problem as you before. Then I found a way out. I visualize the tree on this website. https://itol.embl.de/ I downloaded the taxonomy file, and save it as a txt file. And input the taxonomy file into the tree based on the module they provide. Hope this can help you. …

Hi, @Lu_Yang Thank you for your reply. I tried your idea, it worked to give me a tree. But, the nodes are stilled labelled with hash code, but not my sample ID. So, I cannot read out useful info from this tree. Do you know how the nodes in the tree can be labelled with my Sample IDs? Thanks Dr Y…

Hi, @zejunyan , I am so sorry that I haven't tried the sample ID label. I just tried the taxonomy table. Because for my understanding what the harsh codes you mentioned are the feature ID, each feature ID can only be represented by the taxonomy. I think the sample ID labels you mentioned are anothe…

Hi, @Lu_Yang Thank you for your quick response. I think if we know how ro match each feature ID (i.e. the hash code) to its corresponding sampleID, we can just replace the feature ID with the sample ID, after which, a tree can be drawn with sample ID labelled. My problem is that how to find the ma…

Hi, @zejunyan , I am sorry that I just use one sample to map the tree. Not all samples. Let's wait for @thermokarst reply. Good luck!

[image] zejunyan: My question is that if there is a file that contains information about all the matches between the hash codes and rep sequences? If so, where it can be found? You can tabulate-seqs to determine which sequence belongs to which Feature ID. [image] zejunyan: But, the nodes…

@thermokarst Thank you for you reply. What I mean is that how I can match each feature ID with my SampleID, but not with my sequences. Cheers Dr yan
