Interfaces and workflow of SEEGA. This figure shows the interfaces designed to interact with the underlying algorithms and provides an example of the workflow. All drop-down listboxes are populated with data included in the 3DSlicer scene. a Initial configuration panel of CPE where a fiducial file needs to be selected. b Shows the path of the deetoS binary file provided within SEEGA installation. Once a fiducial file (seeg) has been selected a table is populated with recognized electrodes with valid entry/target pairs. The drop-down list next to the electrode label is used to select its specific model which univocally defines number of contacts and inter-contact distances. An example of what is shown in the 3D View panel wihtin 3DSlicer is provided as inset with post-implant thresholded-CT meshes (ct-post - red) and fiducial file shown as markups (black dots) with letters representing each electrode. c Shows the BZD interface where both BZD takes a volumetric parcellation (aparc+aseg - purple star) and the recontructed data (recon). Examples of such inputs are shown below the interface. d Shows GMPIE interface where the five inputs are defined as left (red) right (green) pial (star) and white (pentagon) surfaces together with segmented channel positions (recon)
