Re^2: A question About Array Indexing

This is a correct assumption! The only variations: 1) The test scalar will be read from an input file. 2) The inclusive ranges are also read in from a text file with the following format:


chrX    1    60000
chrX    60038    60041
chrX    60446    60468
chrX    60689    61799
chrX    62272    62290
chrX    62703    62797

Writing all the inclusive ranges would take a fair amount of time as there are well over 20,000. Can they also be read in within this block of code?

BrowserUk seems to answer these questions pretty well here. Update: Actually, upon closer inspection, I think I would change the statement `my( $start, $end ) = split "\t", $_;` in the `while( <INTERVAL> ) { ... }` loop to `my( undef, $start, $end ) = split "\t", $_;` because the interval data seems to be three-field, tab-delimited records like `chrX 1 60000` in which the first field, to be ignored, is a label of some kind.
