Hey there @turtleonaleash! 🐢

The problem here is that the sample IDs need to be the same in both `bray_curtis_pcoa_results_initial.qza` and `bray_curtis_pcoa_results_final.qza` in order for this viz to work. One way to do that is to relabel the sample ids in your filtered feature tables.

```tsv
# Example QIIME 2 Sample Metadata
sample-id	time pairingid
a initial sample1
b final sample1
c initial sample2
d final sample2
e initial sample3
f final sample3

```

```bash
# create "initial" feature table
qiime feature-table filter-samples \
    --i-table table.qza \
    --m-metadata-file md.tsv \
    --p-where "time='initial'" \
    --o-filtered-table initial-table.qza
# this file should have samples a, c, e

# create "final" feature table
qiime feature-table filter-samples \
    --i-table table.qza \
    --m-metadata-file md.tsv \
    --p-where "time='final'" \
    --o-filtered-table final-table.qza
# this file should have samples b, d, f

# relabel sample ids in initial table
qiime feature-table group \
    --i-table initial-table.qza \
    --p-axis sample \
    --m-metadata-file md.tsv \
    --m-metadata-column pairingid \
    --p-mode sum \
    --o-grouped-table initial-table-relabeled.qza
# this file should have samples sample1, sample2, sample3 (corresponding to a, c, e)

# relabel sample ids in final table
qiime feature-table group \
    --i-table final-table.qza \
    --p-axis sample \
    --m-metadata-file md.tsv \
    --m-metadata-column pairingid \
    --p-mode sum \
    --o-grouped-table final-table-relabeled.qza
# this file should have samples sample1, sample2, sample3 (corresponding to b, d, f)

```

Now, use the newly relabeled tables to run your core-metrics (x2) (don't forget to choose the same even sampling depth). Also, you will need to create a new metadata file for this step, one with the new "pairingid" as your main "id" column.

Keep us posted! :qiime2: 🦖
