Data for electrodes labelling

Description

This dataset includes imaging data and SEEG recordings for 3 subjects. Data include pre- and post- implantation volumes (T1, T2, CT, braincase, DTI) and SEEG acquisitions (ictal, interictal, sleep, electrical stimulation) with corresponding implantation scheme. The dataset is stored in a folder called “Data_for_electrodes_labelling” located inside the “tutorial_data” folder accessible from the Private Space.

The arrangement of files and folders is depicted in Fig.1, while the corresponding naming conventions are outlined in Tab.1. Files and folders are further described in Tab.2 and Tab.3 respectively. For further insights into data formats, refer to Tab.4.
