Don't write it like this.Consider this case:
$ARGV[0] ==0;
then your statement :
my $time_in = $ARGV[0] || STDIN;
should be broken.

Subject: Re: pipe as an argument

Dear Experts,
I am looking for a really efficient way to compute a position weight matrix
(PWM) from a set of strings. In each set the strings are of the same length.
Basically PWM compute the frequency (or probabilities) of bases [ATCG] occur in
each position/column of a string. For example

How do accept pipe as an valid argument in perl, for example:
echo 123456 | ./convert_time.pl
convert_time.pl:
#!/usr/bin/perl
use POSIX qw(strftime);
my $time_in = $ARGV[0];
my $time_out = strftime %Y%m%d, localtime($time_in);
print $time_out\n;
I don't really

Hi Kishore,
The below snippet will get your desired result.

my @structure_name = ();
my $fni = 'd:\Sample.txt' ;
my $fno = 'd:\ashok.txt'

Hi All,
On Unix box we have Oracle 9i and Perl 5.8
Now we are upgrading Oracle to 10g.
In that case we need to re-intsall Perl DBD module.
Is there any other activity that should be taken care of ?
Thanks in advance,
Nilay

Hi,
Suppose I have the output of this command
date +%d.%H
which outputs:
06.11
I want to adjust the last two digits to less 1:
such that it becomes 06.10..
how do I do that?
perhaps something like this.
s/\d+$/(regexp being lookup minus 1/
thanks!

s/\d+$/(regexp being lookup minus 1/
s/(\d+)$/$1-1/e
is going to work, even though it is convoluted and not robust. For
example, '06.00' will become '06.-1'

Hi,
I have a script that I have been running successfully on perl 5.6.1. It uses
Net::SSH to send the code of another perl script to a remote host. I tried
to move the script(s) to a new box running 5.8 and it errors out while
trying to run the cmd method on the command string passed to it. Here

I suspect that this is related to Unicode: A string of eight
characters isn't necessarily eight bytes anymore.

Dear Rob,
I was trying your script with this set of strings:
__DATA__

But how come it returns:
$VAR1 = {
'A' = [ 0, '0.5' ],
'T' = [ 0, 0, 0, 0, '0.5' ],
'C' = [ '0.5' ],
'G' = [ 0, 0, '0.5', '0.5', 0, '0.5' ]
};
Instead of the correct:
$VAR1 = {

I need a regular expression to process some data but

That doesn't look like network order, it looks like plain text.
Didn't you want to use pack()?
