Thanks in advance, Alexandru Tirziu ---

Dear Prof. Bonvin, Yes, I followed the installation instructions as they were described. I think I have some issues regarding the path specification in the activate file. #!/bin/bash export HADDOCK3=/home/alex/share/haddock3-3.0.alpha2 export CNS\_EXE=/home/alex/share/cns\_solve\_1.3/bin/cns if [[-z "{PYTHONPATH}"]]; then PYTHONPATH={HADDOCK3} else PYTHONPATH={PYTHONPATH}:{HADDOCK3} fi export PATH={PATH}:{HADDOCK3}/bin I have untared HADDOCK and CNS on the home/alex/share folder. Am I specifying the path correctly? Thank you in advance! ---

The part of code that you pasted do not contain the exports and the $ in the variables, check if you are running the distributed version: [https://github.com/haddocking/haddock3/blob/master/bin/activate](https://github.com/haddocking/haddock3/blob/master/bin/activate) Also, try checking if `/home/alex/share/haddock3-3.0.alpha2` is in your PYTHONPATH if not, export it directly and try again ``` $ export PYTHONPATH=${PYTHONPATH}:/home/alex/share/haddock3-3.0.alpha2 $ python /home/alex/share/haddock3-3.0.alpha2/bin/haddock3.py ``` ---

Did you check the PYTHONPATH variable? ---

That was the problem, thank you. However, I get this error when I’m trying to run HADDOCK: File “/home/alex/share/haddock3-3.0.alpha2/bin/haddock3.py”, line 250, in valid\_cns = CNS().validate\_cns() File “/home/alex/share/haddock3-3.0.alpha2/haddock/modules/cns/engine.py”, line 28, in validate\_cns raise False TypeError: exceptions must derive from BaseException My activate file: export HADDOCK3=/home/alex/share/haddock3-3.0.alpha2/ export CNS\_EXE=/home/alex/share/cns\_solve\_1.3/intel-x86\_64bit-linux/bin/cns export PYTHONPATH=${PYTHONPATH}:/home/alex/share/haddock3-3.0-alpha2/ Is it about the path that I’m specifying? Thank you! ---

You have to install CNS yourself, recompiling it with the provided code in the cns1.3 folder ---

Prof. Bonvin, I have copied the files from the cns1.3 into the cns bin folder, configured cns\_solve\_env and compiled it with gfortran. I have a .exe in the cns\_solve\_1.3/intel-x86\_64bit-linux/source: cns\_solve-2010061434.exe. Is this the one I need to specify for CNS\_EXE? Should I compile cns with other compiler? Thank you so much! Alexandru Tirziu ---

Yes - but you should copy first the files into the source directory and not bin ---

Now it’s working, running it0. Thank you so much, professor!
