QIIME Tutorials

The QIIME tutorials are documents that illustrate how to use various features of the QIIME. We recommend that all users begin with the QIIME overview tutorial which takes the user through a full analysis of sequencing data. After you’ve begun analyzing your own data, you’ll want to move on to the special-purpose tutorials as needed.

The QIIME development team is very interested in incorporating community-contributed tutorials. Please contact the QIIME Forum if you’re interested in contributing.

Getting started: Sequence processing through OTU tables and phylogenetic trees

• OTU picking strategies in QIIME
• Illumina Overview Tutorial (an IPython Notebook): open reference OTU picking and core diversity analyses
• 454 Overview Tutorial: de novo OTU picking and diversity analyses using 454 data
• Discussion of subsampled open reference OTU picking in QIIME
• Fungal ITS analysis tutorial (an IPython Notebook): open-reference OTU picking
• Preparing raw Illumina data in different formats for use with QIIME
