		+	STAMP is designed to work with the output from classify.seqs (http://www.mothur.org/wiki/Classify.seqs). Note, that you also need a group file (http://www.mothur.org/wiki/Group_file).

	A: STAMP requires all children to have classified parents. Unfortunately, many existing taxonomies do not follow this practice. For example, the following in invalid in STAMP: ''Protebacteria->Gammaproteobacteria->unclassified->Enterobacteriaceae->Escherichia->E. coli'' as the order level designation is ''unclassified''. The easiest way to resolve this is to modify the taxonomy to take into account the last classified rank. Our example could be changed to: ''Protebacteria->Gammaproteobacteria->'''Gammaproteobacteria (order)'''->Enterobacteriaceae->Escherichia->E. coli''.

	A: The utility script [[Media:CheckHierarchy.zip\|checkHierarchy.py]] can be used to identify entries within a STAMP profile that are not strictly hierarchical. These entries must be manually corrected. Often this is simply a matter of fixing up labeling errors or changing entries to indicate they are unclassified (e.g., changing ''uncultured bactrium'' to ''unclassified''). For taxonomic hierarchies, it may also be necessary to append the genus name to species names in order to make these unambiguous. In addition, the parent of all classified entries must also be classified. This can cause problems for some hierarchies such as GreenGenes and SILVA where sequences are assigned to specified OTUs, but intermediate taxonomic ranks are often unclassified. To handle this, I recommend removing the OTU column from the STAMP profile. If this level of precision is needed for certain analyses (e.g., PCA plots), a separate STAMP profile can be constructed which contains only the OTU column as the hierarchy.

-A: STAMP is in active development and we are interested in making it more useful for you. However, like yourself we have a limited amount of free time. If you have a feature suggestion please send an email to Rob Beiko (beiko [at] cs.dal.ca) with as much information as possible. We are open to collaborative efforts if major feature enhancements are being sought. Minor enhancements will generally be done on a first-come-first-serve-most-easily-done basis. If a minor enhancement is time sensitive (i.e., you are preparing a manuscript for publication) please indicate as much in your email.
