in thread change files names bug

You said works for the first files, buy then die with the massage "Can not change sample_ACCTGG.fq to ACCTGG.fq". But when I print $new, it is "LA01.fq" that is correct.

but the code is  rename ($file, $new) or die "Can not change $file to $new, $!\n"; so the error message you quoted is incomplete, it doesn't state the reason it rename didn't work

This reason is everything

    Not to mention that the presented error message shows $new as being ACCTGG.fq, and the OP asserts that it is LA01.fq. Incorrect/incomplete reporting of error messages and other results makes remote diagnosis an exercise in clairvoyance.
