Help extracting single instance of numbers which repeat
Hi, the title isn't very descriptive but it'll be easier to explain what I need if I write out the coordinates from which I need to extract certain information:

Code:
ATOM   2521  C   MAM X  61      44.622  49.357  12.584  1.00  0.00           C
ATOM   2522  H   MAM X  61      43.644  49.102  12.205  1.00  0.00           H

In the 25th and 26th columns (may be some variation from copy/paste editing) there are two-digit numbers between 61 and 68 in the block I've posted above. What I need to be able to do is extract each of those numbers once only and pass each instance into separate, independent variables. Therefore given that there are 8 separate numbers (61-68) I need 8 separate variables corresponding to each.

Any help greatly appreciated. Bash or Python would be easiest for me. Many thanks.

Try:
Code:
awk '{print substr($0,25,2)}' file | sort | uniq

Thank you, that extracts the numbers I need from the file with a 'grep' command at the beginning.

How would I go about assigning them to variables sequentially?

Only print unique field 6
Code:
awk '!x[$6]++ {print $6}' file

print complete line
Code:
awk '!x[$6]++' file

I need to assign each individual number to an individual variable, though.
