Empty directory output in core-metrics

[m-ocejo]

I am importing dada2 table (following the tutorial in its website) to qiime2:

• firstly convert seq_table.txt to hdf5 biom table format (seqtable_qiime.biom).
• then with qiime import tools, convert it to an artifact for qiime2 with this command qiime tools import --input-path seqtable_qiime.biom --type "FeatureTable[Frequency]" --source-format BIOMV100Format --output-path feature-table

I did the same with rep_set.nochimeras.OTUs.fasta qiime tools import --input-path rep_set.nochimeras.OTUs.fasta --output-path rep_seqs-table --type "FeatureData[Sequence]" and Generate the tree for phylogenetic diversity analyses.

Then, I try to run the command qiime diversity core-metrics, it didn´t give any error message. Instead, the terminal showed the 979 sequences (separated by space) of my biom table. When I go to the directory created, it has 0 elements. Both .qza inputs have the semantic type needed.

Any help would much be appreciated! Best!
