Hello, I have a file starting with:
fixedStep chrom=chrX start=1 step=1
0.930
0.955
0.972
0.985
0.993
0.995
0.994
0.990
0.984
0.971
0.942
0.944
0.971
fixedStep chrom=chrX start=200 step=1
0.987
The problem is that, apart from the numbers shown, there are these headers found in the file multiple times. I want to construct a program that stores the position and the value, that means:
1 0.930
2 0.955
etc
whenever you find a line, the numbering continues from the next line, that means:
201 0.987
I have constructed the following code:
#!/usr/bin/perl -w
print "Please enter the filename of your file: ";
$dnafilename = <STDIN>;
chomp $dnafilename;
unless ( -e $dnafilename) {
print "File \"$dnafilename\" doesn't seem to exist!!\n";
exit;
}
unless ( open(DNAFILE, $dnafilename) ) {
print "Cannot open file \"$dnafilename\"\n\n";
exit;
}
while ( <DNAFILE> ) {
unless (/fixedStep chrom=chrX start=(.+) step=1/) {
$counter = $1;
for ($counter = 1; $counter < $. ; $counter++) {
}
print "$counter\t$0\n";
}
}
close DNAFILE;
exit;
Any help would be greatly appreciated!!!

I am sorry...the numbering starts from where it is indicated by the number stored in the field start, that is start = 200 etc...So this means:
200 0.987
etc
