Data Deposition

The following information was supplied regarding data availability:

To implement mSourceTracker, replace the existing '_sourcetracker.py' and 'gibbs.py' files with the modified ones provided as supplemental files. To implement the diagnostic features, use the command --diagnostics in order to run the script and use the command --limit to set the value of the differences between the draws. The default limit was set at 5%. To change it to 10% the user would just enter --limit 0.10.

Here is a command line example:

sourcetracker2 gibbs -i otu_table.biom -m map.txt -o example1/ --diagnostics --limit 0.10

Funding
