split.by: A metadata variable to split the plot by. For example, grouping by "celltype" and splitting by "batch" will create separate plots for each celltype and batch.
idents: Set of identities to include in the plot
label: TRUE/FALSE value to control whether groups are labeled.
repel: Repel labels from each other
show.expected: Plot the expected Tn5 integration frequency below the main footprint plot
normalization: Method to normalize for Tn5 DNA sequence bias. Options are "subtract", "divide", or NULL to perform no bias correction.
label.top: Number of groups to label based on highest accessibility in motif flanking region.
label.idents: Vector of identities to label. If supplied, label.top will be ignored.
