What version of the product are you using? On what operating system?

MDAnalysis0.7.3, Mac Os X 10.6

Please provide any additional information below.

in file TOPParser.py line 83
        numlines = int((float(num)/per_line))
if “num" is divisible by "per_line", the parse will read one more line and 
thus skip the FORMAT line
simply add
if(num % per_line == 0): numlines -= 1
fix the problem
