Abstract: The invention relates to a system for planning and/or tuning a neuromodulation therapy, comprising: a database means for storing a plurality of data sets, each data set comprising: metadata relating to gender data, age data, local field recordings data, microelectrode recordings data, tissue fiber structures data, demographics data and/or anatomy data of a patient, and spatial data relating to distribution of a stimulation field of a neuromodulation probe; input means for entering at least one filter criterion; filter means for applying the at least one filter criterion on the plurality of data sets to generate a filtered subset of the data sets; merging means for merging the spatial data of the filtered subset to generate a functional data set; and visualization means for computing a three dimensional model of the functional data set and for visualizing an image of the three dimensional model.
