Here is the complete problem:
I have two files MAER_FILE and EVAL_FILE
MAER_FILE contains
ITR Max_error Avg_error Min_error
1 0.849197022974602 0.845806355744732 0.843444019245762
2 0.844939386865682 0.841991065818245 0.837942476416068
3 0.844144961481595 0.841099932356234 0.836919185707587
4 0.844144961481595 0.841099932356234 0.836919185707587
5 0.840596405164578 0.838883453436171 0.836919185707587
6 0.839512137681004 0.838072896555497 0.836534486876684
I have to get the last number of the 4th column which is
0.836534486876684 and so i use the following code.
#------
open (MAER_FILE, "MAER_output.txt");
while (<MAER_FILE>) {
chomp;
my @maer_array = split(/\t/);
print "$maer_array[-1]\n";
}
#------
But this gives me the output as the entire 4th column instead of just
the last number.
once i get the last number which is 0.836534486876684 i have to search
for this number in EVAL_FILE which looks like
ITR CHR SUM Error Error(%)
0 1 46.7058362636031 0.849197022974602 84.9197022974602

0 5 46.8269040494763 0.851398255445024 85.1398255445024
0 6 46.9823066656241 0.854223757556801 85.4223757556801
0 7 46.3894210585169 0.843444019245762 84.3444019245762
0 8 46.4279728814877 0.844144961481595 84.4144961481595
0 9 46.4266047910362 0.844120087109749 84.4120087109749
The last number in the previous line must match with one of the number
in the 4 th column of the above file and i should be able to extract
the entire line.
I am not able to store these columns into arrays..either i don't know
perl or arrays. Please help me solve this problem efficiently.
Thanks in advance,
