As @timanix proposed, you could just edit with image editing software (e.g., adobe illustrator) for a quick fix.
I may have a more "out of the box" solution for you though: it sounds like Sample and #SampleID are totally redundant and you are using --m-sample-metadata-column Sample to relabel the samples with the label that you want to display (e.g., in publication). An alternative is to use qiime feature-table group to relabel the sample IDs with any label that you want for publication. Do this:
- Relabel sample IDs with
groupfollowing the steps described in this post. That will create a new feature table where the sample IDs are theSamplenames (or any other metadata information that you want to use to relabel sample IDs) - Input the new table to
heatmapand there should be no need to input metadata to label with additional metadata, so your command would look like this:
qiime feature-table heatmap \
--i-table RELABELED-TABLE.qza \
--p-metric braycurtis \
--p-method average \
--p-cluster both \
--p-color-scheme rocket \
--o-visualization Table_Top25_VA.qzv
Good luck!
