Error in plotting scatter #741

Open amootta opened 2 years ago

amootta commented 2 years ago

Hi, despite specifying an output file for the scatter program, I am still unable to produce any diagrams due to this error:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, webgl, xcb.

Aborted (core dumped)

I am working on a HPC, hence won't be able to connect it to a GUI. I thought it would still be possible to plot to an output file, but this has not been the case for me. Please could you let me know how I can fix this?

Thanks very much

Hi @amootta,

How did you install CNVkit ? Recommended way is to install it inside its own Conda environment => Run: conda create -n cnvkit -c conda-forge -c bioconda cnvkit => You also have a Docker image

Otherwise IMHO this a more an issue related to installation of Qt package => You should not have to deal with that sort of dependencies problems using Conda or Docker => But maybe check thread 1 or thread 2 ?

Hope this helped ! Have a nice day, Felix.
