Hi Guys,
I have a file as follows. Here is my story:
For each field, the string in the 5th column needs to be searched in other fields of the same column and counted if the 1st column of the field is different from that of the primary field. BTW, the unique strings of 1st column need to be considered. Sorry if this is too complicated. Let me clarify it with this example. Here is my file (tab delimited):
Now the counts are reported in a new column:
Thanks a lot in advance!
