16s rDNA ion torrent sequence

Hi guys, I am a very new user of this amazing galaxy platform. My data was single-end 16S rDNA bacteria sequences isolated from plant by using ION TORRENT. I had tried the 16S Microbial Analysis with mothur and Analyses of metagenomics data - The global picture by using my sequences, but it doesn’t seems to work. My data is in fastq format. So, can anyone please suggest me a tutorial/workflow, much appreciated.
