We consider the case of $X$ being certain resolutions of determinantal varieties embedded in $\\mathbb{P}^{d}\\times G(k,n)$. Such resolutions have been modeled, in general, by nonabelian gauged linear sigma models (GLSM). We use the GLSM construction to determine the window categories associated with B-brane transport between different geometric phases using the machinery of grade restriction rule and the hemisphere partition function.
