how to find match between two rows of column in same file using PERL
Hi to all my data looks like this
Code pedigree A B C D E F A B C D E F
X X1 -/- -/- -/- C/C A/A -/- eq eq eq ne eq eq
Y Y1 C/C C/C A/A A/A A/A A/A
1 X1/Y1 C/C C/C A/A A/A Z/Z A/A
2 X1/Y1 C/C -/- A/A A/A A/A A/A
3 X1/Y1 -/- C/C A/A A/A A/A A/A
4 X1/Y1 Z/Z C/C A/A A/A A/A A/A
5 X1/Y1 C/C C/C A/A A/A A/A A/A
First I would like to count total number of different coulmns within a pair of X1 and Y1 across from cloumn A to F, If data is missing (-/-) or unscorable (Z) from cloumns A to F for any one of X1 or Y1 with in a pair of X1Y1 then that column is same between X1 and Y1 else that column is different. I tried folowwing code to do that but not succeed,
#!/usr/bin/perl
print("enter file name to read:\n");
$data=<stdin>;
chop($data);
for($column = 1 ; $column <= 8 ; $column++)
{
for($row = 1 ; $row <= 2 ; $row++)
{
if($row1 eq $row2)
{
$result = "EQ";
}
else
{
$result="NQ";
}
print $result;
}
print "\n";
}
any help would be appreciated
thanks
Well... one way is to load the file into a series of hash tables. One indexed by record number, the others by the column value, with an array of record indexes for the value(that way you also know if two or more rows have the same value, and a list of which records they were). The purpose of the first (indexed by record number) is so that you can look at the entire record where something interesting occurs.
