Hi I am trying to compare two files with chromosome numbers and positions.

For example;

File 1:

I 1000 
I 9009
I 187902

File 2:

I 1080
I 8995
II 578022

I would like to check if the positions of file1 are present in file2 in and around the range of +/- 100 bases and add a third column with "YES/NO".

I tried using awk but i am able to only compare the exact positions.

My output file should look like

I 1080 Yes 
I 8995 Yes
II 578022 No

Any help would be appreciated. Thanks in advance.
