We present $sim$ 173 filaments of galaxies detected in 6dFGS and 2dFGRS out to a redshift of $z <$ 0.05. Selected by mass, we will measure the SFR, morphology and gas content of galaxies within these filaments to test if the filamentary environment provides the right conditions to transform galaxies for the first time. We will also compare how the properties of groups of galaxies within filaments compare to groups not embedded in this large scale structure. Specifically, we aim to test if galaxies are being pre-processed in filaments as they get funnelled into denser environments.
