[mcstas-users] Problems with McStas 3.5.1

Hi again Marcell,


Wrt. the plotting I have tracked down the problem to be an incompatibility between the current code in mcplot-pygtgraph and presence of pyside6 in the conda environment.

Here is what seems to be a functional cure on my system:

1) Take “ownership” (i.e. give yourself all levels of filesystem access) of c:\mcstas-3.5.1\miniconda3

2) Start an “environment terminal”

3) mamba uninstall pyside6


( Interestingly, this dependency has seemingly been pulled in my matplotlib - but only matplotlib-core is in fact needed for mcplot-matplotlib to remain functional… )


I aim to release a new McStas soon (likely 3.5.12 - 3.5.11 is already on conda-forge) that will contain a reasonable fix of the issue.


Let me know if the above workaround helps?


Best
Peter

Dear Marcell,


Thank you for reporting these issues!

I have not seen the mcplot issue earlier, but have just reproduced it with a fresh installation. I will investigate further and come back with an update release soon. (The current code on the repo has the same issue in a fresh installation… Likely an issue related to a recent update of pyqtgraph.)
In the meantime you may potentially use mcplot-matplotlib as a workaround?


The mcdisplay-webgl issue is partially known, please try

1) removing your entire “local folder” C:\\Users\\mwolf\\AppData\\mcstas\\3.5.1\\
2) Start mcdisplay-webgl again (and be patient - this first startup may take minutes)
3) At the end you should be presented with terminal output like the attached - please ctrl + click on the link which should open the browser

If this also fails, mcdisplay-webgl-legacy is available as a fallback solution.

Best and hope this helps,

Peter

Dear all,

yesterady I received a new PC and now installed mcstas3.5.1. for Windows using the introduction on GitHub. Under Mcstas_gui I can run a simulation and can plot it using mcplot-pyqtgraph:

When I now to have a look on a single graph I receive the following messages in the mcgui

<NbL0dhAJmG2VKqME.png>

And I have a second problem when I try to run to run a Trace using mcdisplay-webgl. When I let it run I am not able to copy the error code beause the window directly closes. But under Simulation/Display-3D I reveive the following messages within mcgui:

mcdisplay-webgl --default --no-output-files -n100 Pol_test.instr&
