cooccurrence - interpreting output

I can’t make sense of the output of the cooccurrence command based on the page in the manual.
If I run with default settings, I get:

mothur > cooccurrence(shared=Lc.shared)
Initial c score: 3.46011
average metric score: 3.49
zscore: -4.67546
standard deviation: 0.00639269
Output File Names:

So the initial score is slightly lower than the average score across null matrices. I’m not sure how to interpret the zscore or assess significance based on the standard deviation. If I run this analysis on multiple datasets, can I compare c score across datasets?


There should be a p-value in Lc.cooccurence.summary. Sorry it’s not outputted to the screen - we’ll work on that.
