load_channels(checked=False, test_name=None)

Parameters:

test_name (path to file) – when debugging the function, you can open a channels file from the command line

new_group(checked=False, test_name=None)

Create a new channel group.

Parameters:

• checked (bool) – comes from QAbstractButton.clicked

• test_name (str) – used for testing purposes to avoid modal window

Notes

Don’t call self.apply() just yet, only if the user wants it.

read_group_info()

reset()

Reset all the information of this widget.

save_channels(checked=False, test_name=None)

class wonambi.widgets.channels.ChannelsGroup(chan_name, group_name, config_value, s_freq)

Bases: QWidget

Tab inside the Channels widget.

Parameters:

• chan_name (list of str) – list of all the channels in the dataset

• config_value (dict) – default values for the channels

• s_freq (int) – sampling frequency (to define max of filter)

chan_name

list of all the channels in the dataset

Type:

list of str

idx_l0

list with the channels to plot

Type:

QListWidget

idx_l1

list with the channels to use as reference

Type:

QListWidget

idx_hp

spin box to indicate the high-pass filter

Type:

QDoubleSpinBox

idx_lp

spin box to indicate the low-pass filter

Type:

QDoubleSpinBox

idx_scale

spin_box to indicate the group-specific scaling

Type:

QDoubleSpinBox

idx_reref

it triggers a selection of reference channels equal to the channels to plot.

Type:

QPushButton

idx_color

color of the traces beloning to this channel group (it could be a property of QWidget)

Type:

QColor

Notes

TODO: re-referencing should be more flexible, by allowing other types of referencing.

Use config_value instead of config, because it’s easier to pass dict when loading channels montage.

add_channels_to_list(l, add_ref=False)

Create list of channels (one for those to plot, one for ref).

Parameters:

l (instance of QListWidget) – one of the two lists (chan_to_plot or ref_chan)

get_info()

Get the information about the channel groups.

Returns:

dict – information about this channel group

Notes

The items in selectedItems() are ordered based on the user’s selection (which appears pretty random). It’s more consistent to use the same order of the main channel list. That’s why the additional for-loop is necessary. We don’t care about the order of the reference channels.

highlight_channels(l, selected_chan)

Highlight channels in the list of channels.

Parameters:

selected_chan (list of str) – channels to indicate as selected.

rereference()

Automatically highlight channels to use as reference, based on selected channels.

class wonambi.widgets.channels.ConfigChannels(update_widget)

Bases: Config

Widget with preferences in Settings window for Channels.

create_config()

Placeholder: it’ll be replaced with actual layout.
