I am trying to plot my alpha rarefaction curves at a depth of 10,000 to select a rarefaction depth for my database. The table was generated using dada2 and has been filtered to remove mitochondria, chloroplasts, and unassigned reads.
I have never had an issue with getting curves to appear, but for some reason every time I make the plot it is blank, only showing samples distributed along the y-axis. The ASV table looks normal and has over 3 million reads. Any recommendations?
Here is the code I ran:
qiime diversity alpha-rarefaction
--i-table table.qza
--i-phylogeny rooted-tree.qza
--p-max-depth 10000
--m-metadata-file metadata.txt
--o-visualization alpha-rarefaction-r10000.qzv
