pout2prot converts Percolator output files to protein group and subgroup files (Occam or anti-Occam) as input for
Prophane. In pout2prot, the user can choose between two protein grouping strategies: Occam’s razor and anti-Occam’s 
razor. Occam’s razor is based on the principle of maximum parsimony, and provides the smallest set of proteins that 
explains all observed peptides. Here, proteins and their associated taxonomy and functions are expected to be 
present in the sample, but proteins that by chance could not be matched to a unique peptide are falsely discarded. 
This algorithm is for example used in the X!TandemPipeline. On the other hand, anti-Occam’s razor is based on the 
maximal explanatory set of proteins. Here, any protein that contains at least one identified peptide, will be 
provided in the protein list. This algorithm is used in for example the MetaProteomeAnalyzer (MPA). Importantly, 
while it is important to mention which grouping algorithm was used, there is no way to determine which algorithm is 
more correct.

pout2prot is also available as an online web application (see https://pout2prot.ugent.be) that's run entirely in 
your browser (you don't need to install anything to get started).
