What I'm typing is untested, is just to give you some ideas. In any
case, this error is because I meant the first_line variable to contain
an array, but I misplaced the call to split:

Replace this:

>>   first_line = file.readline
>>   first_line_times = first_line.chomp.split("\t").each_slice(2).map

with this:

first_line = file.readline.chomp.split("\t")
first_line_times = first_line.each_slice(2).map

Jesus.
