I am trying to extract data that is in a single column to split it into 3
columns. The data is cyclic and has 3 variables, a time, a data point and a
random number. These simply run abcabcabcabc down the column and i would
like to get all of the a's into a column, all of the b's into another column
and all of the c's into a third column.

any ideas?
