in reply to file header change

Where exactly are you stuck?

Did you manage to open the file

Can you print the contents of the file from your script

Assuming that you can, all you need is:

if( $line =~ />contig_(\d+)\s/ ) { print ">$1\n"; } else { print "$lin +e\n"; }

    thanks tmharish.. i used the following, but its not working.. :
    use strict; use warnings; sub read_file { my( $filename ) = <STDIN>; my @lines; sub read_file { my( $filename ) = <STDIN>; my @lines; open( FILE, "< $filename" ) or die "Can't open $filename : $!" +; { if( @line =~ />contig_(\d+)\s/ ) { print ">$1\n"; } else { print "$line\n"; } }

    :-(

      , but its not working..

      I am not surprised.

      Why do you have the same function defined twice? The second time inside the first??

      Create two functions, one to get the file name and the other to read the file, modify the contents and print it

      CALL the functions

      And finally try to run your code and get rid of the syntax errors.

        got it.. thanks tmharish for ur cooperation..
