For example, a method or system (via actions performed by a processor) can include receiving a name of an anatomical or physiological target or a name of a disease or disorder; receiving a clinical goal; and using at least 1) the anatomical or physiological target or disease or disorder and 2) the clinical goal, selecting a set of stimulation parameters. Another method or system (via actions performed by its processor) can include receiving a first set of stimulation parameters; receiving a command to alter the first set of stimulation parameters that does not include, or is not composed exclusively of, a numerical value for any of the stimulation parameters; and modifying the first set of stimulation parameters to create a second set of stimulation parameters based on the command. ## Claims ### Claim 1 A system for identifying a set of stimulation parameters, the system comprising: a computer processor configured and arranged to perform the following actions: providing a model of a lead comprising a plurality of electrodes, wherein the plurality of electrodes comprises a plurality of segmented electrodes forming at least one set of segmented electrodes, wherein each set of segmented electrodes comprises two or more of the segmented electrodes disposed around a circumference of the lead at a same longitudinal position along the lead;
