HFO marking label for ieeg-1 (intracranial electroencephalography 1)


Hello everybody,
Re: HFO marking label for ieeg-1 (intracranial electroencephalography 1)

Hi Mostafa,
The prospective definition of a clinically relevant HFO is based on the automated detection. (We only review events visually to reject artifacts.)
Simultaneous fast ripples and ripples (FRandR) had the highest clinical relevance as defined by their power to predict seizure freedom.
So FRandR are the ground truth.
You should train your algorithm on FRandR. Make sure to benchmark your results against seizure freedom.
Best,
Johannes

Hi Johannes,
Are there any meta-data available for this dataset? like SOZ, Resected area, or seizure freedom data?

Hi Mostafa,
Please have a look at our publication https://www.nature.com/articles/s41598-017-13064-1
Table 1 lists the resected area (RA) anatomically and the postsurgical seizure freedom (ILAE scale) for each patient.
In more detail, the supplementary material (Table 1S) lists all channel locations that were resected (highlighted in red). https://doi.org/10.1038/s41598-017-13064-1
The seizure onset zone (SOZ) as defined by the epileptologists is included in the resected channels.
For easy access, I attach the supplementary Table 1S here.
All the best,
Johannes
