Temple University EEG Data Management Project
Temple University's College of Engineering and Temple University Hospital System have collaborated on the Clinical EEG Database Project, led by Sung In Choi. The project involves processing EEG data, analyzing the data files, and transferring them using specific steps outlined in the protocol. The archived CD/DVD contains sampled EEG data handled by EEG technicians. Quick steps for data transferring and processing involve saving files, generating reports, and de-identifying EDF+ files. The project includes detailed test reports, conversion of file formats, and patient ID mapping. Utilization of EEG folders and subfolders ensures organized data management for patients involved in the study.

EEG Data Processing Steps Data Directory Structure
ANALYSIS OF EEG DATA Original Data Processed Data File Format * . e and *.edf+c * . edf+c View Program Nicolete EEG viewer version 5.71 Nicolete EEG viewer version 5.71 MATLAB Information Patient Information Test information EEG signal Diagnostic tags (Annotation) Test information EEG signal Diagnostic tags (Annotations) Archived Format CD/DVD Portable Drive
Archived CD/DVD Sampled EEG by EEG technician Copy and covert files (run script in each folder) Generate Test and Impedance report EEG TUH Reserve contains the original data file *.e & *.edf+c 0000 Patient ID Mapping Required Run script to generate ID map through .edf+c file in original data folder EEG NEDC reserve contains de- identified data file *.edf+c 0001
Quick Steps of Transferring Data 1. Save .e file from CD/DVD to TUH reserve EEG0000 2. Open .e file with Nicolet viewer 5.71 3. Generate reports from the tool option (.mhtml format) 4. Generate EDF+ file using the option of Nicolet software Automated by the key simulation program Automated by the de-identification python script 5. Run script to de-identify the EDF+ files and save in EEG0001
Test report Patient information Physician s note EEG technician and equipment information Impedance report Impedance value of electrodes Annotation location information EEG report Clinical History and Diagnosis Formal EEG report
Converting .e .edf TO .mhtml .xlsx word or pdf .xlsx Re-assigning Medical Record Number is replaced by NEDC patient ID and subject ID (eg.12345678 tuh000000001 123456789a) Generating Master sheet of the patient ID mapping Separate folder for each patient
