EEG DATA PROCESSING STEPS ANALYSIS OF EEG DATA Original Data Processed Data File Format *. e and *. edf+c View Program 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
EEG DATA PROCESSING STEPS Archived CD/DVD • Sampled EEG by EEG technician Copy and covert files (run script in each folder) Generate Test and Impedance report EEG 0000 • TUH Reserve contains the original data file *. e & *. edf+c Patient ID Mapping Required Run script to generate ID map through. edf+c file in original data folder EEG 0001 • NEDC reserve contains deidentified data file *. edf+c
EEG DATA PROCESSING STEPS Quick Steps of Transferring Data 1. Save. e file from CD/DVD to TUH reserve EEG 0000 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 5. Run script to de-identify the EDF+ files and save in EEG 0001 Automated by the key simulation program Automated by the de-identification python script
EEG REPORT DATA • 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
KEY-FEATURE OF AUTOMATIC PROCESS • Converting. e. mhtml TO word or pdf • Re-assigning . edf. xlsx Medical Record Number is replaced by NEDC patient ID and subject ID (eg. 12345678 tuh 00001 123456789 a) • Generating Master sheet of the patient ID mapping Separate folder for each patient
