I have downloaded the file from the website https://zhanglab.ccmb.med.umich.edu/PSSpred/ and do everything as the tips. But there was an error when I try to run the script PSSpred.pl(I have changed the $db: $db="/data3/yzz/machine/nr/"; #where NR sequence database is).
I guess it may caused by the file named nr.tar.gz in the wedsite https://zhanglab.ccmb.med.umich.edu/PSSpred/. Because when I open a file in the dolder, the text is : Warning! This is NOT an NR database.This is a fake NR database generated with swissprot release 2017_06. It is compatible with PSSpred program. But it is known to generate worse result than the original nr database.
So what can I do to fix the issue?
