Error message " library files are not complete" while running the ./runI-TASSER.pl script?

Question

[Neha shri]

Hello ,

I am new to protein modelling using I-tasser package. I have manually downloaded the I-tasser library files and decompressed them into a directory of I-tasser package.

When I am running the runI-TASSER.pl script,

The error says-

Your library files are not complete, please download library with the script download_lib.pl.

I also tried running the script download_lib.pl, but it stays unresponsive. I have checked the files and the path for every input carefully. Could anyone please point me towards how to resolve this?

Thank you in advance

This could be a lot of things. I'd suggest creating a backup copy of the download_lib.pl file, then tinkering with the original file by adding debug points (echo out stuff at various stages) to find where exactly execution gets stuck. You can also use Data::Dumper for debugging, but I've found incremental edits adding plain echo statements easier to work with.
