Hi Brian!
Thanks for the example however since i want to have the code read from a 
file and write to another file i have done this
File.open("/home/george/output.csv","w") do |f|
 src = ""
 File.open('/home/george/sequences/results_processed.csv').each do 
|rows|
  src << rows
  end
  rows = src.split("\n\n").collect { |b| b.split("\n") }
  m = rows.collect { |r| r.size }.max
  m.times { |i| f.puts rows.collect { |r| r[i] }.join(",") }

but it prints out the same old original file without modifications

Any ideas?
