Hi, Here is the explanation of task I want to perform. 1. match the value of column 2 of file 1 with the value of column 1 of file 2 (i.e. chr11). and then fetch all lines of file2 which have chr11 value.

2. make the varables -500 and +500 of value 4 of file 1 (i.e. 650). From 150 to 1150 select a sliding window of 50 with window size 100. i.e. 150-250, 200-300, 250-350, 300-400....1050-1150.

3. Count the lines of file2, on the basis of value in the second column of file2, which lies in these windows....

4. For this examples... The answer should be

150 250 0

250 350 0

350 450 0

450 550 0

550 650 5

650 750 1

750 850 0

850 950 0

950 1050 0

1050 1150 0

1150 1250 0
