Hello ITASSER Team,

I have been interested in testing out the CR-I-TASSER since its release, however, the web-version appears to take a bit of time to run samples. I wanted to install a local version and was trying to follow the instructions from

From following the MANUAL.txt, on step 2 it states to "'' is provided in the package for automated library download and update of the libraries." I was able to input the directory and start running the script. However, I would hit an error in downloading the NR database.
'Downloading NR database...
System call failed: at ./ line 108'

Looking into this script, in line 108, it mentions '' as the location, but I don't believe I can access this. Would there be a potential workaround or way to update this?

Additionally, it looks like there are other downloads, some of them are from but are the updated links in

Thank you,

Hello Andrew,

Thank you so much for pointing out the bug. We have updated the and now should work fine. Please re-download the package and find the updated script. Also please do not concern about "" vs "". You could run a test like "wget -o log -c ... BSITES.bsr" which should be able to download BSITES.bsr to your local.

Hello Zhang,

Thank you for changing the script. I have tried again with the new script, and most of the libraries were working/downloaded correctly. The one issue that I encountered with the new script is it complains about the metaclust_2017_05.fasta.gz file. In the log it states, 'ERROR: cannot verify's certificate, ... Issue certificate has expired.

It did suggest to attach --no-check-certificate to the call in order to download the .gz file, and this did get the file, but then it didn't extract the file. I believe that changing the extraction method (tar -zxvf to gzip -d) did allow the fasta file to download correctly. I think that after this change, CR-I-TASSER should have all of the libraries required to run. However, when doing a basic run:
"$pkgdir/I-TASSERmod/ -libdir /home/yourname/ITLIB -seqname example -mapname -datadir /home/yourname/CR-I-TASSER-1.0/example"

I keep encountering 'error: without MSA file generate!'. This is early on in '2.0 run DeepMSA'. Are there any other steps that you could suggest?

Best Regards,
