Question: Write a program that takes as input an alignment, and outputs the PWM and the information content of the PWM. To prevent prob = 0

Write a program that takes as input an alignment, and outputs the PWM and the information content of the PWM. To prevent prob = 0 from happening, add a pseducount 1 for each nucleotide. i.e., p_A = (c_A + 1) / (c_A + c_C + c_G + c_T + 4), where c_A is the number of A's observed in the column. (It is best to implement the main functionality as a function so that you can reuse it in Problem 4 or possibly also Problem 3.) Apply your program on the following alignment and report the results. Also use the web tool enoLogos to compute the sequence logo. Make sure you set %GC to "equiprobable". Click on textout to check the probability matrix and information content there. Do they match your results?
