Picrust prediction problem

Hi everyone
I am trying to perform a picrust analysis, my OTU tables are short (between 30 and 60 OTUs) because they come from a network analysis, when I load my data everything works perfect, in the picrust analysis I get the notification that the analysis was successful, but when I download the functionalprof_picrust all the resulting KO have 0 as relative abundance.
Can someone help me?

Hello,

Could you please make sure that the annotation was performed using the right database? Currently, MicrobiomeAnalyst uses the 12May2012 version of Greengenes database for normalization of 16S copy numbers and gene content predictions.

If you still have problem, you can send the files to yao.lu5@mail.mcgill.ca for trouble shooting.
