in thread Help with pushing into a hash

Thanks. That removed 2 of the error lines. The first 2. Now these are left:

Use of uninitialized value $1 in hash element at C:\Users\Jems\Desktop +\Perl\test\test2script.plx line 26. Use of uninitialized value $1 in hash element at C:\Users\Jems\Desktop +\Perl\test\test2script.plx line 27. Use of uninitialized value $1 in hash element at C:\Users\Jems\Desktop +\Perl\test\test2script.plx line 28.

lines 26, 27 and 28 are:

for ( read_file $uniprot ) { /(.{6})\s+.+=([^\s]+)/; push @activline, "$1 | $2 | $activ{$1}\n" if $activ{$1}; #26 push @antioxline, "$1 | $2 | $antiox{$1}\n" if $antiox{$1}; #27 push @toxinline, "$1 | $2 | $toxin{$1}\n" if $toxin{$1};#28

The format for $uniprot is the same as for $test. I.E.

    The message:

    Use of uninitialized value $1...

    Means that the regex is not matching some lines in your data set. Here are two options:

    say if !/(.{6})\s+.+=([^\s]+)/;

    This will show you the lines that are not matching, so you can adjust your regex, if needed.

    next unless /(.{6})\s+.+=([^\s]+)/;

    This will just skip those lines that don't match the regex.

      Well the file's format was wrong at some parts. So yeah, that. I'll go see if I can fix the file. Thanks so much again!

        You're very welcome! Return if you encounter more issues...
