I’m using q2cli version 2017.10.0
on Ubuntu 16.04.3
and run the following command:
qiime diversity core-metrics-phylogenetic --i-phylogeny rooted-tree.qza --i-table tabl.qza --m-metadata-file metadata.txt --output-dir core_metrics_output --p-sampling-depth 1000 --p-n-jobs 20
I’m getting the following error:
Plugin error from diversity:
Weighted UniFrac is not parallelizable
Debug info has been saved to /tmp/qiime2-q2cli-err-ohnrm9rv.log
I do not get the same error when using the same command but leaving out --p-n-jobs 20
This appears to be a bug, where qiime diversity core-metrics-phylogenetic
is trying to provide the weighted unifrac
function with multiple threads, but the function throws an error.
