Read a data file. The line of code DataSet myData = ReadDataFile ("../data/demo.seq"); reads data from the file demo.seq (located in the data directory) and stores the data in a structure called myData. The line of code uses two Hy-Phy commands, DataSet and ReadDataFile. The first part of the program statement, DataSet myData, simply tells Hy-Phy to create a structure named myData that will hold a data set. The second part of the statement, ReadDataFile("../data/demo.seq") actually reads and processes the data in the file demo.seq.
