PEWO can be easily extended by community developers whenever a new tool is published or made available. Recently, a group of researchers from Göttingen in Germany proposed and implemented the integration of the tool App-Spam.
App-SpaM, which stands for /Alignment-free phylogenetic placement algorithm based on SPAced-word Matches/, can be installed with conda or from github. App-SpaM is alignment-free and uses spaced seeds. More on bioRxiv.
Only a few months after PEWO’s first release, App-Spam is now part of PEWO.
