Fenchel-Nielsen coordinates play a central role in constructing partition functions for theories of class S with gauge group SU(2). Having an analogue of these coordinates for higher rank gauge groups is a first step in finding partition functions for strongly coupled gauge theories of the Minahan-Nemeschansky type. We find such a generalization through the formalism of spectral networks and the non-abelianization map, that was originally introduced by Gaiotto, Moore and Neitzke to find a better understanding of BPS states in the theories of class S. This is joint work with Andy Neitzke.
