-Sliding windows are also useful to compare two (or more!) sets of data. This can be very valuable when you want to compare differential expression in two different conditions. When you have two different sliding windows sets, this function merges them into one, where each window contains the two pieces of information. You may want to plot the data afterwards using the *plot transcript list* function.
