Problem encoutered with FFParam tool installation using UBUNTU terminal

Question

[ranjeet]

Good Day,

Currently I'm working on molecular dynamics stuff and I have a necessity to alter some of the parameters to suit my protein simulation model fit within an virtual interacting environment known as box. For that purpose, I planned to use FFParam but I can't open up my ffparam-gui even though I followed the same installation steps as mentioned in the manual provided by the developer in their official website: HERE

It's look like some problem arises with the python modules used to run the tool

May someone help me to solve this issue? Thanks in advance.

Apparently, ffparam-gui uses the Qt library to generate the graphical user interface. To my best knowledge, Qt is not installed by default in Ubuntu (only in Kubuntu), so you might need to install it on your system via the package manager.

As you can see in the description for e.g. PyQt5, you need to ensure that Qt’s qmake tool must be on PATH. So try if which qmake works and if not, the error might resolve by installing Qt:

sudo apt-get install qt5-default qt5-qmake qtbase5-dev-tools

Thanks. The issue has been resolved but now I'm having a new issue can you help me to figure this for me as well.

Try:

 sudo apt-get install libosmesa6

 export PYOPENGL_PLATFORM=osmesa

It's throw this error message now:

AttributeError: 'NoneType' object has no attribute 'glGetError'
