neurone_loader.loader¶
Classes¶
neurone_loader.loader.BaseContainer () |
A metaclass that provides properties for accessing data shared between all subclasses. |
neurone_loader.loader.Phase (*args, **kwargs) |
Represents one recording phase of one NeurOne session in one NeurOne Recording |
neurone_loader.loader.Recording (*args, **kwargs) |
Represents one NeurOne Recording and contains all of the recording’s sessions |
neurone_loader.loader.Session (*args, **kwargs) |
Represents one session in one NeurOne Recording and contains all of the session’s phases |
Provides classes to load, represent and export data recorded with the Bittium NeurOne device.

BaseContainer
[source]¶ A metaclass that provides properties for accessing data shared between all subclasses. I cannot be used itself as it is not implementing all required methods of its abstract superclass.
-
channels
[source]¶ Note
This property is a lazy property. For details see
lazy.Lazy
Returns: ordered list of all channel names, read from the session protocol Return type: list[str]
-
drop_channels
(channels_to_drop)[source]¶ Remove specified channels from loaded data. Dropped channels will be remembered and when data is cleared from memory and reloaded from disk the channels will get removed again. To get them back create a new object of this type to reload from disk.
Parameters: channels_to_drop (list[str]) – names of channels to drop
-
-
class
neurone_loader.loader.
Phase
(*args, **kwargs)[source]¶ Represents one recording phase of one NeurOne session in one NeurOne Recording
Parameters: -
data
[source]¶ Note
This property is a lazy property. For details see
lazy.Lazy
Returns: recorded data with shape (samples, channels) in µV Return type: numpy.ndarray
-
drop_channels
(channels_to_drop)[source]¶ Remove specified channels from loaded data. Dropped channels will be remembered and when data is cleared from memory and reloaded from disk the channels will get removed again. To get them back create a new object of this type to reload from disk.
Parameters: channels_to_drop (list[str]) – names of channels to drop
-
event_codes
¶ Returns: all event codes used in the data as int32 in an numpy.ndarray Return type: numpy.ndarray
-
events
[source]¶ Note
This property is a lazy property. For details see
lazy.Lazy
Returns: recorded events with Revision, Type, SourcePort, ChannelNumber, Code, StartSampleIndex, StopSampleIndex, DescriptionLength, DescriptionOffset, DataLength, DataOffset, StartTime, StopTime Return type: pandas.DataFrame
-
n_samples
¶ Returns: the number of channels, inferred from the binary recording’s file size Return type: int
-
preload
()¶ Use this function to call all properties constructed with
lazy.Lazy
. It can also be used to reload all lazy properties without deleting them first.Example: >>> @preloadable >>> class Test: >>> @Lazy >>> def lazy_attribute(self): >>> print('lazy function called') >>> return 'lazy return' >>> >>> test_object = Test(preload=False) # The lazy property is not evaluated on initialization >>> test_object.preload() lazy function called >>> print(test_object.lazy_attribute) # The stored attribute is returned lazy return >>> test_object.preload() # All properties are reloaded even though already stored lazy function called

class
neurone_loader.loader.
Recording
(*args, **kwargs)[source]¶ Represents one NeurOne Recording and contains all of the recording’s sessions
Parameters: path (str) – path to the recording recording folder -
channels
¶ Returns the channels used in all sessions and makes sure they’re equal
Returns: ordered list of all channel names, read from the session protocols Return type: list[str]
-
data
[source]¶ Note
This property is a lazy property. For details see
lazy.Lazy
Returns: concatenated data of all phases of all sessions with shape (samples, channels) in µV Return type: numpy.ndarray Warning
Calling this replaces the data attribute of the contained phases and sessions with a view on the concatenated data to save memory. Keep this in mind when manipulating the contained sessions or phases.
-
drop_channels
(channels_to_drop)[source]¶ Remove specified channels from loaded data. Dropped channels will be remembered and when data is cleared from memory and reloaded from disk the channels will get removed again. To get them back create a new object of this type to reload from disk.
Parameters: channels_to_drop (list[str]) – names of channels to drop
-
event_codes
¶ Returns: all event codes used in the data as int32 in an numpy.ndarray Return type: numpy.ndarray
-
events
¶ Returns: concatenated events of all phases of all sessions with Revision, Type, SourcePort, ChannelNumber, Code, StartSampleIndex, StopSampleIndex, DescriptionLength, DescriptionOffset, DataLength, DataOffset, StartTime, StopTime Return type: pandas.DataFrame
-
n_channels
¶ Returns the number of channels used in all phases and makes sure they’re equal
Returns: the number of channels, read from the session protocol Return type: int
-
n_samples
¶ Returns: sum of the number of samples, inferred from the binary recording’s file size, of all phases of all sessions Return type: int
-
preload
()¶ Use this function to call all properties constructed with
lazy.Lazy
. It can also be used to reload all lazy properties without deleting them first.Example: >>> @preloadable >>> class Test: >>> @Lazy >>> def lazy_attribute(self): >>> print('lazy function called') >>> return 'lazy return' >>> >>> test_object = Test(preload=False) # The lazy property is not evaluated on initialization >>> test_object.preload() lazy function called >>> print(test_object.lazy_attribute) # The stored attribute is returned lazy return >>> test_object.preload() # All properties are reloaded even though already stored lazy function called
