Hi dear list, I wonder if somebody can help me with this. I have a text file with 300 rows and around 300000 columns and I need to insert a column that has the number 1 in every row. This new column should be placed between columns 6 and 7.
As an example: I would want to insert a column (consiting just of the number 1 in every row, as in column 6) between columns 6 and 7. 847 847 0 0 2 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T 847 847 0 0 2 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T 847 847 0 0 2 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T 847 847 0 0 2 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T 847 847 0 0 2 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T 847 847 0 0 2 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T So the new table would look like this: 847 847 0 0 2 1 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T 847 847 0 0 2 1 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T 847 847 0 0 2 1 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T 847 847 0 0 2 1 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T 847 847 0 0 2 1 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T 847 847 0 0 2 1 1 G G T C A G T T C G A C C C G C A A A G G G G A C A T T You can also look at this problem as duplicating column 6.
