Hello,
I am trying to import phylogenetic information into QIIME2 for diversity analysis, but I am having some issues. The main error message I get is "The table does not appear to be completely represented by the phylogeny". I have a FeatureTable[Frequency] with taxonomic assignments from a .biom file I exported from MEGAN. It is in this format:
"rows":[{"metadata":{"taxonomy":["d__Bacteria"]},"id":"2"},{"metadata":{"taxonomy":["d__Bacteria","s__uncultured bacterium"]},"id":"77133"},{"metadata":{"taxonomy":["d__Bacteria","p__Bacteroidetes"]},"id":"976"},{"metadata":{"taxonomy":["d__Bacteria", ....
"columns":[{"metadata":{},"id":"ES9-1"},{"metadata":{},"id":"ES1-2"}],"matrix_type":"dense","matrix_element_type":"int","shape":[93,2],"data":[[0.0,43404.0],[12123.0,0.0],[0.0,0.0],[0.0,0.0],[352628.0,1969263.0],[0.0,0.0],[10786.0,5120.0],[23463.0,41556.0],[18384.0,0.0],[0.0,12236.0],[0.0,0.0],[0.0,0.0],[14066.0,0.0],[0.0,0.0],[73603.0,234769.0],[35838.0,11903.0],[0.0,0.0],[0.0,0.0],[0.0,0.0],[0.0,0.0],[0.0,0.0],[0.0,0.0],[0.0,0.0],[0.0,0.0],[0.0,0.0],[1243603.0,1729832.0],[149361.0,57626.0],[34720.0,0.0],[40593.0,29055.0],[53655.0,57874.0],[0.0,96118.0],[0.0,0.0],[0.0,0.0],[0.0,0.0],[5441.0,73132.0],[8567.0,0.0],[28942.0,207225.0],[0.0,0.0],[0.0,0.0], ....
I try to export a .tre file from MEGAN and use it with this frequency table, but the error I mentioned above appears. I also tried using the ncbi.tre file from MEGAN, but the same issue occurs. The files are below. I think the issue is incompatibility between how taxonomies are represented (ID versus written out), but I am not sure. I am not looking for an exact recipe for importing these phylogeny files, but I am trying to diagnose the issue. Does anyone know what the problem is?
