scale structure. Such studies are important to test the already well developed TTT, and to asses the possibility that such correlations affect the results of cosmic shear measurements. Regarding the former, TTT produces noisy predictions due to the non-linear nature of the accretion processes of clumpy matter [@Vitvitska1; @Porciani1], on scales below the coherent scale of flows predicted by linear theory. The second tests for the effects on cosmic shear studies used to analyse weak lensing, may answer whether there is an intrinsic alignment in the structure traced by galaxies that could result in a spurious contribution to the shear power spectrum [@Hirata1; @Bridle1; @Takada1; @King1; @King2; @Heymans1; @Heymans2; @Brown1; @Catelan4; @Crittenden1; @Croft1; @Jing1]. Several authors have searched for galaxy alignments in the super-galactic plane [@Vauco1], extending out to several tens of megaparsecs from our Galaxy, and more recently on large galaxy surveys [@Hirata1; @Hirata2; @Lee1; @Lee2; @Mandel1]. @Lee1 claim a direct evidence of an alignment between galaxy position angle in 2MRs and the tidal field deduced from galaxy positions.

An interesting approach to the analysis of galaxy alignments is to use the radial direction to the centres of voids as characteristic directions in the large scale structure. It is
