Error 'float' object has no attribute 'type' in OTU clustering


I am trying to cluster OTUs in qiime and am getting the following error:

‘float’ object has no attribute ‘type’

I am running qiime2 2018.11 installed on Miniconda.

qiime vsearch cluster-features-de-novo \

--i-sequences /Users/xxx/Desktop/Data/qiime_tutorial_defaultdenoiseseqs.qza \
--i-table /Users/xxx/Desktop/Data/qiime_tutorial_defaultdenoisetable.qza \
--p-perc-identity 99 \
--o-clustered-table /Users/xxx/Desktop/Data/qiime_tutorial_defaultOTUtable.qza \
--o-clustered-sequences /Users/xxx/Desktop/Data/qiime_tutorial_defaultOTUseqs.qza \

Traceback (most recent call last):

AttributeError: ‘float’ object has no attribute ‘type’

Thank you!

Thanks for speaking up, @erin13!
This should be an easy fix for you :crossed_fingers:, and your post helped us identify a couple of bugs.

Your argument to --perc-identity must be in the range 0-1.

We'll be fixing up type-checking so that future users get helpful error messages (issue 1), and will look into solutions for displaying required parameter ranges so other people don't run into this problem (issue 2).

Happy :qiime2:-ing!

Thanks for your help!
