Hi,




I'm using McStas to simulate the instrument. I uninstalled my old version of McStas and installed the version 2.7.1. But there is a problem with the 'plot' function. I can't use it. Error prompt always pops up when compiling. The error is as following:

 'mcplot-pyqtgraph C:\mcstas-2.7.1\source_test\13b20220704_20221031_165658

Can you give me some advice on how to solve this problem?

Hello Lisa,


This is actually a well-known problem with the recent Python 3.10 release and the 2.7.1/3.1 releases, communicated to the mcstas-users mailinglist (https://mailman2.mcstas.org/pipermail/mcstas-users/2022q3/001478.html) website (https://www.mcstas.org) on September 23rd.

To correct both this mcplot-related problem and a similar mcgui-related problem, please

replace the following files within your installation folder:

$MCSTAS/tools/Python/mcgui/viewclasses.py - please replace by this new version: https://raw.githubusercontent.com/McStasMcXtrace/McCode/mccode-3/tools/Python/mcgui/viewclasses.py
$MCSTAS/tools/Python/mccodelib/pqtgfrontend.py - please replace by this new version https://raw.githubusercontent.com/McStasMcXtrace/McCode/mccode-3/tools/Python/mccodelib/pqtgfrontend.py

New stable releases of McStas should be released during November/December this year.

Best and sorry for the inconvenience,

Peter Willendrup

Subject: [mcstas-users] A couple of new bugs - with workarounds/fixes
Message-ID: <EE7B8F0B-5221-4243-B182-38999C8F2D0D@fysik.dtu.dk>

Dear all,



Firstly, several users have reported a bug related to our pyqtgraph plotter, that ends up crashing with e.g.

File "C:\mcstas-2.7.1\lib\tools\Python\mcplot\pyqtgraph\plotfuncs.py", line 203, in plot_Data2D

img.scale(dx,dy)
TypeError: scale(self): too many arguments'

If you are in this situation, replace your plotfuncs.py with this new version:

https://raw.githubusercontent.com/McStasMcXtrace/McCode/master/tools/Python/mcplot/pyqtgraph/plotfuncs.py



Secondly, if are on a Mac and upgrade to macOS 13 Ventura (intel/x86_64), your already installed Python tools of McStas/McXtrace and /Application bundles may not work after the upgrade.

A workaround is to:

  *   In a terminal, start your ?McStas or McXtrace shell" (e.g. run mcstas-3.1-environment, /Applications/McXtrace-1.7-environment.command or /Applications/McXtrace-3.0.app/Contents/Resources/mcxtrace/3.0/environment)
  *   Issue the command

export PATH=$MCSTAS/miniconda3/bin:$PATH

  *   Next, you may issue the your gui command with either
     *
        *

mcgui or mxgui


New releases of McStas and McXtrace are in preparation and should be released during November or December.


Best and sorry for the inconvenience,

Peter Willendrup

Subject: [mcstas-users] McStas 2.7.1 Installation on Ubuntu/Linux
Message-ID: <5c2ac5e2-73c8-678d-fbad-65abb3129c68@ill.fr>

Hi all (and especially Peter),

I have a short question/remark concerning the installation of McStas 
2.7. 1 on Ubuntu (22.04 in my case)

Following the instructions on:
https://github.com/McStasMcXtrace/McCode/blob/master/INSTALL-McStas-2.x/Linux/debian/README.md

The two commands

sudo apt-get install mcstas-suite-python

sudo apt-get install mcstas-suite-python-ng

both install McStas 3.1.

To get the 2.7.1 install one can use the command:

sudo apt-get install mcstas-suite-python=2.7.1


The downside: during a regular SW-update McStas thinks it is out-dated and installs the (the most current) 3.1. version and the 2.7.1 becomes broken.
To fix it McStas (3.1.) has to be un-installed and 2.7.1 re-installed (with the command as above).

Can this be fixed somehow from your side : i.e. the repository maintainers?

Thanks in advance,

Best,

Richard

Hello again,


* For 2.7.2 users on arm64 macOS - if you downloaded before today:
Last night I found a small mishap in the macOS Silicon / arm64 release of McStas 2.7.2:
- It actually contained a set of 3.x binaries and tools.

A fresh build of 2.7.2 for arm64 macOS was immediately uploaded.


* For Ubuntu users where your browser can not access the documentation:
Please consult https://github.com/McStasMcXtrace/McCode/issues/1378 for a solution


* Further, for those of you on CentOS I have decided to released a set of packages:
https://download.mcstas.org/mcstas-3.2/Linux/centos/
https://download.mcstas.org/mcstas-2.7.2/Linux/centos/

These are the last packages released for CentOS and are not offered from the repo - they must be manually installed.


Best,
Peter Willendrup
