Determine if the following text contains a data availability statement. Answer with 'yes' or 'no'.

Text: The recording protocol was designed to avoid possible interference with the clinical EEG recording . To attach conventional disc electrodes , the patient 's scalp was cleaned with Nuprep and EEG electrodes were placed at the 10 - 20 International Electrode System locations using Ten-20 paste . Collodion was used to hold all the EEG electrodes in place . To record tEEG simultaneously with the EEG , TCREs were placed behind the conventional disc electrodes in locations close to the 10 - 10 sites using Ten-20 paste . The ground was placed on the forehead and the reference was placed at the Oz location . EEG was recorded with the Comet AS40 system ( Grass Technologies , West Warwick , RI , USA ) at 200 samples per second with the 70 Hz low - pass filter and 60 Hz notch filter active . The tEEG data were pre - amplified with the gain equal to 6 , amplified , band - pass filtered 1 - 100 Hz with 60 Hz notch filter active , and digitized with an Aura LTM-64 system ( Grass Technologies , West Warwick , RI , USA ) at 200 samples per second . Recording sessions for both patients lasted for about six hours and took place around 7:00 a.m. to 1:00 p.m. According to the NINN recording protocol patients were sleep deprived the night before recording and signed an additional informed consent form for the antiepileptic drugs dosage to be reduced by half the day before the recording . Board - certified neurologists reviewed the recorded data determining the seizure onset time and duration for each seizure .<|eot_id|><|start_header_id|>assistant<|end_header_id|>
