Hello again @SciCatalyst,
Note: I have changed the title since this is really a SEPP error, and an error you are getting from QIIME 2, not from PICRUST itself, per se.
I am pinging @gmdouglas since these are tutorial files causing this error, in case he wants to take a look.
Given that these are tutorial files, I agree with you that this is probably a memory error, but you can follow the debugging steps in this forum topic (note the debug
and verbose
flags) to get more diagnostic details:
let us know what you find!
