Hi,
I`m running Ubuntu 20.04
I`m getting this error when I start assign:
QT error: 3
QT error: <PyQt5.QtCore.QMessageLogContext object at 0x7fef13a83190>
QT error: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

I have the required libraries.
Has anyone else had this issue?
Thanks,

Hi Jo,
not entirely sure what is going on here, but given that our Ubuntu build was done on Ubuntu 16.04, it could be that the environment it provides is simply too old and we`ll need to do a new build for it to work on 20.04. We`ll investigate.
Best wishes,
Vicky
Hmm, this seems to run on our Ubuntu20.04.3 without any issues...
Is it worth trying to download and unpack again? Perhaps something got corrupted during the process?
Vicky
Hi Vicky,
I think it may be a problem with an Ubuntu update, it would seem that I can`t run any other v3 versions either but I could previously. I`m downloading 3.0.4 again and I`ll see whether that helps in any case...

Hi Vicky,
So reinstalling 3.0.4 and also the ubuntu qt5 installation didn`t work. Is it possible for me to compile analysis from scratch?
Cheers,
Jo
Hi Jo,
sorry to hear you are having issues running 3.0.4
I have attached a .zip containing the scripts required to install/compile the dependencies.
Download the scripts.zip to your 3.0.4 folder ~/software/ccpnmr3.0.4 and unzip.
It should add a folder called Internal
from a terminal, navigate into the folder with
cd internal/scripts
There are a list of bash scripts in here. The main one you need is installMiniconda.sh
The environment we use is called Miniconda which supplies the specific python and its dependencies.
To run the script, type
./installMiniconda.sh
and follow the questions.
It will ask to download and install miniconda3 to your home directory as ~/miniconda3
and then create the environment by downloading the required files.
There will be a series of questions:
Do you want to download/install the latest Miniconda?
answer y, or n if you already have the ~/miniconda3 folder
Do you wish the installer to prepend the Miniconda install
location to PATH in your ~/.bash-profile?
answer y the first time (you can run the script as many times as needed) to add ~/miniconda3/bin to your PATH
Do you want to install a new environment?
answer y the first time, or if you want to replace it. answer n if you only want to change the symbolic link (the next step)
This will create ~/miniconda3/envs/ccpn-v3.0.4 which is the python environment.
Do you want to create symbolic link?
answer y to replace the miniconda folder in the AnalysisV3 folder to point to the new environment folder above,
in your case ~/software/ccpnmr3.0.4/miniconda
Before following the last step below, check if the program is working with the new environment, open a new terminal, and run
~/software/ccpnmr3.0.4/bin/assign
Finally, if the above step has worked, from the internal/scripts folder again, run
./compileCCode.sh
to compile the last bits of C code, I have not fully checked this last step on Ubuntu 20.04 yet though
Sorry this seems long, but hopefully that describes the steps you need
Kindest regards
Ed

Hi Ed,
Thanks for your help, the instructions worked fine. However, I was still getting the same error. But subsequently removing pyqt and reinstalling it has done the trick, assign is now running.
