Parameters:fname (str) – the path to the filename

close()

close and release the file

get_channel_count() → int

get the number of channels stored in the file

get_channel_info(index: int) → Tuple[str, str, str]

get information about a specific channel

Parameters:index (int) – the index number for the channel Returns:the information where tuples contains three strings: channel label, channel reference and unit, i,e,: (‘Cz’, ‘ref’, ‘uV’) Return type:Tuple[str, str, str]

get_sample_count()

returns the number of samples in the file as int

returns the sample frequency of the data as int

get_samples(fro: int, to: int) → List[List[float]]

load a range of samples from the file

Parameters:

• fro (int) – the first sample to load
• to (int) – the last sample to load

Returns:

data – a list with length samples containing a list of values for each channel

Return type:

List[List[float]]

Example

data = cnt.get_samples(0,1) # return the first sample for all channels
