I ran my beta diversity command in Qiita and downloaded the .tsv matrix file so I could use it to run the longitudinal first-distances in QIIME2. However, when I try to run it, I get this error: distance-matrix_unweighted_skin.tsv is not a QIIME archive. So I attempted to convert the tsv file to a biom file but I get the error: column index exceeds matrix dimension. Then I converted the tsv to a txt file and tried to use that to create a biom table but I got the same error. Any ideas on what I can do to use this artifact to run this QIIME2 command? Thanks!
Distance matrices are not biom tables. You need to import these as a
qiime tools import \ --input-path distance-matrix.tsv \ --type 'DistanceMatrix' \ --output-path distance-matrix.qza
@antgonza may have further insight — I do not know the specific format of distance matrices that are output by QIITA.
