SeqAn executables are installed and the install location is in the system path; whether I choose "Find in Path" or use "Find in Directory" and browse to the install directory, none of the SeqAn applications are "filled in".
At the moment we're not sure which nodes we might need; I'd expect our users to be able to select what they need - which could in principle be any or all of the SeqAn tools.
I was able to work out the correct tool for some of the nodes; not sure about these:
FxBamCoverage & FxFastqStats;
MasonFragSequencing, MasonGenome, MasonMaterializer; MasonSimulator & MasonVariator.
