The GliGal4 line used in Schmidt et al., 2012, J. Neurosci. 32(22): 7466--7476 (FBrf0218491) was generated by the Auld lab by converting the P{lacW}GliJ29 lacZ enhancer trap insertion (FBti0009224) into a GAL4 insertion using the protocol described in Sepp and Auld, 1999, Genetics 151(3): 1093--1101 (FBrf0107981).
