Here's another option:

use strict;
use warnings;

for my $file (<*.ptseq>) {
    my ($baseName) = $file =~ /^(.+)\.[^.]+$/;

    my $textFile1 = $baseName . '1.txt';
    my $textFile2 = $baseName . '2.txt';

    print "$file ->\t$textFile1\t$textFile2", "\n";
}

Output from my dir:

fileA.ptseq ->    fileA1.txt    fileA2.txt
fileB.ptseq ->    fileB1.txt    fileB2.txt
fileC.ptseq ->    fileC1.txt    fileC2.txt
fileD.ptseq ->    fileD1.txt    fileD2.txt
