Plots nucleltide secondary structure as helices in arc diagram
gghelix(helix_data, color_by = "length", overlap = FALSE)a data frame. The file of nucleltide secondary structure and then read by ggmsa::readSSfile.
generate colors for helices by various rules, including integer counts and value ranges one of "length" and "value"
Logicals. If TRUE, two structures data called predict and known must be given(eg:heilx_data = list(known = data1, predicted = data2)), plots the predicted helices that are known on top, predicted helices that are not known on the bottom, and finally plots unpredicted helices on top in black.
