im encountering a problem with too long fasta headers. They get truncated at the 20th position by a program (TargetP) im using.
What remains are tousands of entrys named "ConsensusfromContig1".
Is there any software or any script i can use to rename the headers in a way that they are 20 characters long and still able to get identified? I have only found scripts for truncating too long headers so far. The desired naming for the example would be something like 10000|3144/1451-1467:0 .
I would be grateful for any help provided.
