Result after classifying.otu

Hi

I have used mothur to perform analysis on data from 16S data using the “mothur miseq SOP”
I have used cluster.split to cluster sequences into OTUs.
I was wondering whether the number of sequences in each of these sampels are too low?? Or is this as expected??
I was just assuming these numbers to be higher.?

Thank you very much!

The numbers in cons.tax.summary is just the number of otus that classify to that group. There may be a way to have the cons.tax.summary incorporate info from the count table, but I don’t know how.

If you want the *.cons.tax.summary to reflect the number of sequences in each OTU that classify to a given taxon, you can use the basis parameter, http://www.mothur.org/wiki/Classify.otu#basis. The default of the basis parameter is the number of OTUs that classify to the given taxon.
