Apparently, you are rewriting the value of the @alphaid and @betaid arrays
on each of the loops after the s///.
What are you trying to do with:
@alphaid = $line;
push(@alphaid,$_);
I'd try only:
push(@alphaid, $line);
if I understood correctly.
Cheers,

I am sure there are better ways as I am learning as well, but how
about doing something like this. This is assuming both arrays have the
same number of elements.
open MYFILE, f1.txt;
for (0..$#alpha) {
print MYFILE $alphaid[$_]\t;
print MYFILE $betaid[$_]\n;
}

You are missing the FAM header files.
On some Linux distros, that might be installed as libfam-dev package, not

Thanks John. OOps I did not mentioned one condition while writing the
regular expression.
condition is : If after last dot(.) there are three digit then don't do
anything but if after last dot(.) there are no exactly three digit then
replace that dot(.) and all digits after that dot with space.
Perl already has all the info from the previous lstat command, using _
is more efficient in that it doesn't have to do another system call.

Instead of using two arrays just use one Array of Arrays.
