The Global Feature Extractor (gFEX) subsystem of the ATLAS Level 1 calorimeter trigger will identify large-radius jets, which are typical of Lorentz-boosted objects. Here I present results from calibrating gBlocks, groups of towers, using offline R=0.4 jets. Dijet Monte Carlo simulation samples at a center of mass energy of 13 TeV are used to find calibration factors. Effects on energy resolution are studied as well.
