Extracting rows from a text file if the value of a column falls between a certain range

Hi,

I have a file that looks like the following:

Code:
10      100080417       rs7915867       ILMN_1343295    12      6243093 7747537 
10      100190264       rs2296431       ILMN_1343295    12      6643093 6647537 
10      100719451       SNP94374        ILMN_1343295    12      6688093 7599537 
10      101217090       rs6584276       ILMN_1343295    12      6688093 6947537

I want to extract all the lines where the value in column 2 is within +/- 1,000,000 the range given by the values in columns 6 and 7 (i.e. either between the values in columns 6 and 7, or less than 1,000,000 smaller from the value in column 6, or less than 1,000,000 greater from the value in column 7) Thanks!

If I understood correctly, you could try this:

Code:
awk '$2>($6-1000000) || $2<($7+1000000)'

While thinking twice, I came to the conclusion that the above should better read

Code:
awk '$2>($6-1000000) && $2<($7+1000000)'
