Hi all, 

we are happy to provide full simulation environments for free (at Binder) for the McStas/neutrons and McXtrace/xrays software. This information is available at [ http://mcxtrace.org/ | http://mcxtrace.org/ ] and [ http://mcstas.org/ | http://mcstas.org/ ] . 

* McStas : [ https://mybinder.org/v2/gh/McStasMcXtrace/mcstas-binder/master?urlpath=desktop | https://mybinder.org/v2/gh/McStasMcXtrace/mcstas-binder/master?urlpath=desktop ]

Hi Wanju Luo,

I can see two solutions:

1- start Binder with the JupyterLab interface through the link 
<https://mybinder.org/v2/gh/McStasMcXtrace/mcstas-binder/master?urlpath=lab> 
(for neutrons) and 
<https://mybinder.org/v2/gh/McStasMcXtrace/mcxtrace-binder/master?urlpath=lab> 
(for X-rays), then click on the Desktop icon/tile on the right panel. 
You can drag-n-drop files in the JupyterLab Tab (left panel showing the 
content of the Binder VNC session).

2- open Firefox and use any DropBox/NextCloud/etc cloud system, as well 
as a mere web-mail.

Emmanuel.

Hi all,

Let me add that both of the McStas and McXtrace are also on dockerhub, meaning that you can easily run them on your own computer after installing Docker, using either:


  *

docker run -p 8888:8888 docker.io/mccode/mcstas-2.7.1-3.1:1.0<http://docker.io/mccode/mcstas-2.7.1-3.1:1.0>

  *

docker run -p 8888:8888 docker.io/mccode/mcxtrace-1.7-3.0:1.0<http://docker.io/mccode/mcxtrace-1.7-3.0:1.0>


By adding -v $HOME/work:/home/jovyan/work in the above commands, you will mount a shared folder between ?work? on your physical machine and ?work? within the docker image.

Best,
Peter

Message-ID: <aed05d99-827e-fae8-47bd-055dfd185fb9@tum.de>

Hello McStas team!


my name is Abdel, I'm currently working with McStas 2.7.1 to simulate 
the SANS-1 beamline at FRM-II.

I'd like to use the handy ITERATE tool in McStas to slice one beam guide 
into 54 parts, but I still have some difficulties with that. I have 
tried running the template from E. Farhi, <Test_Jump_Iterate>, but it 
only sets/displays two guides instead of the intended 30.

I'd be glad if you could help me figure it out, ideally via the template 
file.

Thank you in advance,

Abdel A.

To be completely honest with you, JUMP + ITERATE is in fact a GOTO-mechanism - more or less a hack. :)
(see also https://xkcd.com/292/)

There is only one guide element in play, plus ?magic teleportation? of the neutron from end to start of that guide element. This does in fact ?work?, but will naturally display one guide element only.

My recommendation will always be to avoid JUMP since its implications can be misleading and hard to debug.

I suggest you in fact put all of the 54 guide elements in place, but make use of COPY to ease the copy-pasting. :)

(In McStas 2.7.1 and earlier this means actual c-code-duplication and longer compile-time, but in 3.1 the compilation-time in such cases is much improved, due to the use of TRACE-functions.)


Best,
Peter

I tried both 2.7 and 3 versions, both show the same behaviour.


For Info, pip3 list returns the following

PyQt5-Qt5???????????????????????? 5.15.2
PyQt5-sip????????????????????????? 12.9.1


Any help appreciated!

Dear Jean-Francois,


OK, thank you for the information.

Which exact Linux Mint are you on? As I remember Mint is a Debian-variant - and was our Debian packages your method of installation? In this situation, the dependencies are assumed to be resolved using Python modules provided by the OS itself, not conda or pip.

The problem seems to relate to problems in the scintilla-based editor, which version of libqscintilla is installed?

What I get on a Ubuntu 20.04 LTS (from the OS, not pip) is
ii  libqscintilla2-qt5-15   2.11.2+dfsg-6 amd64        Qt5 port of the Scintilla source code editing widget


Is your Mint python ?in mint condition? ( ;-) ) or has it been enriched with pip-stuff installed at the system level? In the latter case it may be worth checking how the code behaves in a ?pure? environment.


Now to a more practical attempt at a solution:

I would try upgrading to 2.7.1 and/or 3.1 which have a new configuration-option in mccode_config.json that allows to avoid using scintilla all together:

mcstas-3.1 env ~ $ mcrun --write-user-config
loading system configuration
userconfig saved to /Users/pkwi/.mcstas/3.1/mccode_config.json

and then edit mccode_config.json so that

    "QSCI": ?0"

This should avoid any reference to the qscintilla lib and widgets.


Best and let me know how it goes,

Peter

I tried both 2.7 and 3 versions, both show the same behaviour.


For Info, pip3 list returns the following

PyQt5                                5.15.6
PyQt5-Qt5                         5.15.2
PyQt5-sip                          12.9.1


Any help appreciated!

Dear Peter,


thanks for your suggestions!

Synaptic shows:

 ??? libqscintilla2-qt5-15 2.11.2+dfsg-6

My mint (20.3) is fresh, but not mint ;0)

Regarding python, usually I pip install as a normal user. I am not quite 
sure what then gets precedence here... mcstas will call the system 
installed package, right ? Or does it inherit from the user calling mcgui?


I am now running mcstas 2.7.1 from ppa and actually cannot find execute 
mcrun as such:

 ??? jfmoulin at jfm17:~$ mcrun --write-user-config

 ??? Command 'mcrun' not found, did you mean:

 ? ??? command 'crun' from deb crun (0.12.1+dfsg-1)
 ? ??? command 'mcron' from deb mcron (1.0.8-1build1)

 ??? Try: sudo apt install <deb name>


mcrun.pl is actually found at usr/bin/mcrun.pl though. Link missing?


Cheers,


Jean-Fran?ois

Hi again,


I am quite sure your user environment could affect the Python environment that e.g. mcgui ?sees?.

Your mcrun should in fact be sitting in the same directory where mcgui resides? But maybe you started it via a Desktop launcher?


Running (e.g.)
mcstas-3.1-environement

should give you a shell which knows about the Python mcrun?

Alternatively call mcrun with the full path, this should be something like
/usr/share/mcstas/3.1/bin/mcrun

mcrun.pl is ?so much last year? ;-)


Best,
Peter

Dear Jean-Francois,


OK, thank you for the information.

Which exact Linux Mint are you on? As I remember Mint is a Debian-variant - and was our Debian packages your method of installation? In this situation, the dependencies are assumed to be resolved using Python modules provided by the OS itself, not conda or pip.

The problem seems to relate to problems in the scintilla-based editor, which version of libqscintilla is installed?

What I get on a Ubuntu 20.04 LTS (from the OS, not pip) is
ii  libqscintilla2-qt5-15   2.11.2+dfsg-6 amd64        Qt5 port of the Scintilla source code editing widget


Is your Mint python ?in mint condition? ( ;-) ) or has it been enriched with pip-stuff installed at the system level? In the latter case it may be worth checking how the code behaves in a ?pure? environment.


Now to a more practical attempt at a solution:

I would try upgrading to 2.7.1 and/or 3.1 which have a new configuration-option in mccode_config.json that allows to avoid using scintilla all together:

mcstas-3.1 env ~ $ mcrun --write-user-config
loading system configuration
userconfig saved to /Users/pkwi/.mcstas/3.1/mccode_config.json

and then edit mccode_config.json so that

    "QSCI": ?0"

This should avoid any reference to the qscintilla lib and widgets.


Best and let me know how it goes,

Peter

well,


This is what I see with a print statement at the beginning of mcgui.py

PyQt5.__file__ : 
/home/jfmoulin/.local/lib/python3.8/site-packages/PyQt5/__init__.py

So, yes, this is my pip installed Qt


Trying your sugestion:

 ??? jfmoulin at jfm17:~$ mcstas-2.7.1-environment

 ??? The new shell started here is now set up for running this version 
of mcstas:

 ??? McStas version 2.7.1 (Oct. 04, 2021)
 ??? Copyright (C) DTU Physics and Risoe National Laboratory, 1997-2021
 ??? Additions (C) Institut Laue Langevin, 2003-2021
 ??? All rights reserved

 ??? To end using this version of mcstas, exit this shell.
---- (in this same? shell)

 ??? jfmoulin at jfm17:~$ mcrun

 ??? Command 'mcrun' not found, did you mean:

 ? ??? command 'mcron' from deb mcron (1.0.8-1build1)
...

so, still no joy.

I tried here under 2.7.1 which is the one I installed after having the 
problem with 3.1 in the first place.


And, BTW, what is a desktop launcher ;0) (i.e, I called mcrun from a 
shell as reported in my previous mail. No clicking, I swear.)

Moreover, I seem to be stuck in the perl past for mcrun:


 ??? jfmoulin at jfm17:~$ which mcgui
 ??? /usr/share/mcstas/2.7.1/bin/mcgui
--------------------------------------------------------------------------------

 ??? jfmoulin at jfm17:~$ ls /usr/share/mcstas/2.7.1/bin/
 ??? cif2hkl????????????? mcformat??? mcpl2ssw? mcstas postinst
 ??? mcdisplay-mantid.pl? mcgui?????? mcpltool? mcstas_errmsg pymcpltool
 ??? mcdoc.pl???????????? mcpl2phits? mcrun.pl? phits2mcpl ssw2mcpl

I just installed Qscintilla form pip (as a user and I can now run mcgui).

Will now start playing.

Thanks for your help!

Hi,


Hmm. Did you install the packages independently or using the ?python metapackage?, i.e.
mcstas-suite-python (or mcstas-suite-python-ng in the case of 3.1)

You may also try to directly install the python mcrun package

apt-get install mcstas-tools-python-mcrun-2.7.1


Best,
Peter

well,


This is what I see with a print statement at the beginning of mcgui.py

PyQt5.__file__ : /home/jfmoulin/.local/lib/python3.8/site-packages/PyQt5/__init__.py

So, yes, this is my pip installed Qt



Trying your sugestion:

    jfmoulin at jfm17:~$ mcstas-2.7.1-environment

    The new shell started here is now set up for running this version of mcstas:

    McStas version 2.7.1 (Oct. 04, 2021)
    Copyright (C) DTU Physics and Risoe National Laboratory, 1997-2021
    Additions (C) Institut Laue Langevin, 2003-2021
    All rights reserved

    To end using this version of mcstas, exit this shell.
---- (in this same  shell)

    jfmoulin at jfm17:~$ mcrun

    Command 'mcrun' not found, did you mean:

      command 'mcron' from deb mcron (1.0.8-1build1)
...

so, still no joy.

I tried here under 2.7.1 which is the one I installed after having the problem with 3.1 in the first place.


And, BTW, what is a desktop launcher ;0) (i.e, I called mcrun from a shell as reported in my previous mail. No clicking, I swear.)

Moreover, I seem to be stuck in the perl past for mcrun:


    jfmoulin at jfm17:~$ which mcgui
    /usr/share/mcstas/2.7.1/bin/mcgui
    --------------------------------------------------------------------------------

    jfmoulin at jfm17:~$ ls /usr/share/mcstas/2.7.1/bin/
    cif2hkl              mcformat    mcpl2ssw  mcstas         postinst
    mcdisplay-mantid.pl  mcgui       mcpltool  mcstas_errmsg  pymcpltool
    mcdoc.pl             mcpl2phits  mcrun.pl  phits2mcpl     ssw2mcpl

Hi again,


I am quite sure your user environment could affect the Python environment that e.g. mcgui ?sees?.

Your mcrun should in fact be sitting in the same directory where mcgui resides? But maybe you started it via a Desktop launcher?


Running (e.g.)
mcstas-3.1-environement

should give you a shell which knows about the Python mcrun?

Alternatively call mcrun with the full path, this should be something like
/usr/share/mcstas/3.1/bin/mcrun

mcrun.pl is ?so much last year? ;-)


Best,
Peter

Dear Peter,


thanks for your suggestions!

Synaptic shows:

My mint (20.3) is fresh, but not mint ;0)

Regarding python, usually I pip install as a normal user. I am not quite sure what then gets precedence here... mcstas will call the system installed package, right ? Or does it inherit from the user calling mcgui?


I am now running mcstas 2.7.1 from ppa and actually cannot find execute mcrun as such:

    jfmoulin at jfm17:~$ mcrun --write-user-config

    Command 'mcrun' not found, did you mean:

      command 'mcron' from deb mcron (1.0.8-1build1)

    Try: sudo apt install <deb name>


mcrun.pl is actually found at usr/bin/mcrun.pl though. Link missing?

Dear Jean-Francois,


OK, thank you for the information.

Which exact Linux Mint are you on? As I remember Mint is a Debian-variant - and was our Debian packages your method of installation? In this situation, the dependencies are assumed to be resolved using Python modules provided by the OS itself, not conda or pip.

The problem seems to relate to problems in the scintilla-based editor, which version of libqscintilla is installed?

What I get on a Ubuntu 20.04 LTS (from the OS, not pip) is
ii  libqscintilla2-qt5-15   2.11.2+dfsg-6 amd64        Qt5 port of the Scintilla source code editing widget


Is your Mint python ?in mint condition? ( ;-) ) or has it been enriched with pip-stuff installed at the system level? In the latter case it may be worth checking how the code behaves in a ?pure? environment.


Now to a more practical attempt at a solution:

I would try upgrading to 2.7.1 and/or 3.1 which have a new configuration-option in mccode_config.json that allows to avoid using scintilla all together:

mcstas-3.1 env ~ $ mcrun --write-user-config
loading system configuration
userconfig saved to /Users/pkwi/.mcstas/3.1/mccode_config.json

and then edit mccode_config.json so that

    "QSCI": ?0"

This should avoid any reference to the qscintilla lib and widgets.


Best and let me know how it goes,

Peter

Hi,


Good that you found a solution / hack . :-) I do think you should also make sure you have e.g. the Python mcrun, I believe this is what mcgui will be configured to use...

In regard to the tool layer, this is almost identical in 2.7.1 and 3.1. And 3.1 can be worth investing a little time in e.g. because of the (NVIDIA) GPU support.

See the relevant sections in https://github.com/McStasMcXtrace/McCode/wiki in regard to conversion of instruments (and your own comps).


Best
Peter

Hi,


Hmm. Did you install the packages independently or using the ?python metapackage?, i.e.
mcstas-suite-python (or mcstas-suite-python-ng in the case of 3.1)

You may also try to directly install the python mcrun package

apt-get install mcstas-tools-python-mcrun-2.7.1

Peter

well,


This is what I see with a print statement at the beginning of mcgui.py

PyQt5.__file__ : /home/jfmoulin/.local/lib/python3.8/site-packages/PyQt5/__init__.py

So, yes, this is my pip installed Qt



Trying your sugestion:

    jfmoulin at jfm17:~$ mcstas-2.7.1-environment

    The new shell started here is now set up for running this version of mcstas:

    McStas version 2.7.1 (Oct. 04, 2021)
    Copyright (C) DTU Physics and Risoe National Laboratory, 1997-2021
    Additions (C) Institut Laue Langevin, 2003-2021

    To end using this version of mcstas, exit this shell.
---- (in this same  shell)

    jfmoulin at jfm17:~$ mcrun

    Command 'mcrun' not found, did you mean:

      command 'mcron' from deb mcron (1.0.8-1build1)
...

so, still no joy.

I tried here under 2.7.1 which is the one I installed after having the problem with 3.1 in the first place.


And, BTW, what is a desktop launcher ;0) (i.e, I called mcrun from a shell as reported in my previous mail. No clicking, I swear.)

Moreover, I seem to be stuck in the perl past for mcrun:


    jfmoulin at jfm17:~$ which mcgui
    /usr/share/mcstas/2.7.1/bin/mcgui
    --------------------------------------------------------------------------------

    jfmoulin at jfm17:~$ ls /usr/share/mcstas/2.7.1/bin/

Hi again,


I am quite sure your user environment could affect the Python environment that e.g. mcgui ?sees?.

Your mcrun should in fact be sitting in the same directory where mcgui resides? But maybe you started it via a Desktop launcher?


Running (e.g.)
mcstas-3.1-environement

should give you a shell which knows about the Python mcrun?

Alternatively call mcrun with the full path, this should be something like
/usr/share/mcstas/3.1/bin/mcrun

mcrun.pl is ?so much last year? ;-)


Best,
Peter

Dear Peter,


thanks for your suggestions!

Synaptic shows:

    libqscintilla2-qt5-15 2.11.2+dfsg-6

My mint (20.3) is fresh, but not mint ;0)

Regarding python, usually I pip install as a normal user. I am not quite sure what then gets precedence here... mcstas will call the system installed package, right ? Or does it inherit from the user calling mcgui?


I am now running mcstas 2.7.1 from ppa and actually cannot find execute mcrun as such:

    jfmoulin at jfm17:~$ mcrun --write-user-config

    Command 'mcrun' not found, did you mean:

      command 'crun' from deb crun (0.12.1+dfsg-1)
      command 'mcron' from deb mcron (1.0.8-1build1)

    Try: sudo apt install <deb name>


mcrun.pl is actually found at usr/bin/mcrun.pl though. Link missing?

Dear Jean-Francois,


OK, thank you for the information.

Which exact Linux Mint are you on? As I remember Mint is a Debian-variant - and was our Debian packages your method of installation? In this situation, the dependencies are assumed to be resolved using Python modules provided by the OS itself, not conda or pip.

The problem seems to relate to problems in the scintilla-based editor, which version of libqscintilla is installed?

What I get on a Ubuntu 20.04 LTS (from the OS, not pip) is
ii  libqscintilla2-qt5-15   2.11.2+dfsg-6 amd64        Qt5 port of the Scintilla source code editing widget


Is your Mint python ?in mint condition? ( ;-) ) or has it been enriched with pip-stuff installed at the system level? In the latter case it may be worth checking how the code behaves in a ?pure? environment.


Now to a more practical attempt at a solution:

I would try upgrading to 2.7.1 and/or 3.1 which have a new configuration-option in mccode_config.json that allows to avoid using scintilla all together:

mcstas-3.1 env ~ $ mcrun --write-user-config
loading system configuration
userconfig saved to /Users/pkwi/.mcstas/3.1/mccode_config.json

and then edit mccode_config.json so that

    "QSCI": ?0"

This should avoid any reference to the qscintilla lib and widgets.


Best and let me know how it goes,

Peter

Hi Thx,

well yes the gui starts but mcrun seems to have rights issues.

/bin/sh: 1: mcrun: Permission denied

I will uninstall and retry with 3.1 (which I initially planned to use 
anyway) and report, but unfortunately not in the next hours.

Cheers,

JF
