Here you can find some code accompanying our project on quiver Dressians.
The input file for gfan to compute the quiver Dressian in Example 4.4 can be downloaded here
The polyhedral complex can be computed using gfan_tropicalintersection, the output can be downloaded here
Here you find the tropicalizations of all different primary components of the tropical Grassmannian of Example 4.4 as a zip-file
The example for a quiver Dressian with nonrealizable points in ambient dimension 3 for fields with trivial valuation can be found here
