Hello,

As your requirement is still not clear to me. What I assume is you need to enter a new column to a file. If that is the requirement please try the following code.

lets say there is file named file_name which have columns as follows.

Code:

ID GENE Newcol pos start end

Command is:

Code:

awk 'NR==1 {$2=$2 "\t""Newcol"; print; next}' file_name

Output should be:

Code:

ID GENE Newcol pos start end

So after running the command a newcol is being added. Bot sure if this may help you. Please get back to us in case you need more assistance for same.




Thanks,
