convert x/y/z electrode montage positions to spherical coordinate representation. output is a matrix

Takes a kwargs named tuple of Key => NamedTuple and merges the fields with the defaults

df_timebin(df, Δbin; col_y=:erp, fun=mean, grouping=[])

Split or combine dataframe according to equally spaced time bins

• df AbstractTable with columns :time and col_y (default :erp), and all columns in grouping;
• Δbin bin size in :time units;
• col_y default :erp, the column to combine over (with fun);
• fun function to combine, default is mean;
• grouping (vector of symbols/strings) default empty vector, columns to group the data by before aggregating. Values of nothing are ignored.

Helper function converting a matrix (channel x times) to a tidy dataframe with columns :estimate, :time and :label

eegtopoplotseries!(fig, data::DataFrame, Δbin; kwargs..) In place plotting of topoplot series see eegtopoplotseries(data, Δbin) for help

function eegtopoplotseries(data::DataFrame, Δbin; y=:estimate, label=:label, col=:time, row=nothing, figure = NamedTuple(), combinefun=mean, rowlabels = false, collabels = false, topoplot_attributes... )

Plot a series of topoplots. The function automatically takes the combinefun=mean over the :time column of data in Δbin steps.

• The data frame data needs the columns :time and y(=:erp), and label(=:label). If data is a matrix, it is automatically cast to a dataframe, time bins are in samples, labels are string.(1:size(data,1)).
• Δbin in :time units, specifying the time steps. All other keyword arguments are passed to the EEG_TopoPlot recipe. In most cases, the user should specify the electrode positions with positions=pos.
• The col and row arguments specify the field to be divided into columns and rows. The default is col=:time to split by the time field and row=nothing. Useful to split by a condition, e.g. ...(..., col=:time, row=:condition) would result in multiple (as many as different values in df.condition) rows of topoplot series.
• The figure option allows you to include information for plotting the figure. Alternatively, you can pass a fig object eeg_topoplot_series!(fig, data::DataFrame, Δbin; kwargs..).
• row_labels and col_labels indicate whether there should be labels in the plots in the first column to indicate the row value and in the last row to indicate the time (typically timerange).

key word argumets (kwargs)

• normalize (default: nothing): if :minmax, normalize each axis to their respective min-max range.

Defining the axes

• Default: ...(...; mapping=(; x=:channel, y=:estimate)). One could overwrite what should be on the x and the y axes.
• By setting ...(...; mapping=(; color=:colorcolumn)) one defines conditions splitted by color. The default color is defined by ...(...; visual=(; color=:black)).
