[mcstas-users] two problems with 2.0RC2

[Evgeny Moskvin]

Dear Peter,

it works, thank you!
But another problem appeared. It happens at some point during "sim-edit-sim... etc" iterations. Suddenly the run menu appears without parameters list, and the log is:

[emoskvin:17843] *** End of error message ***

It happens not only with my own files, but also with mcstas examples. And of corse it's not possible to start simulations, because if you press "run" button (in gui), the system waits for user to enter parameters in the back (terminal window which is not available for typing in it). Restarting mcgui helps with build in examples, but doesn't with my file.
I tried to run without gui by

mcrun H2_D2.instr

doesn't work either, the error message is

Traceback (most recent call last):
  File "/usr/local/bin/mcrun", line 9, in <module>
    from mcstas import McStas
  File "/usr/local/lib/mcstas-tools-python-mcrun-2.0RC2/mcstas.py", line 6, in <module>
    import yaml
ImportError: No module named yaml

Hope my explanations are clear (more or less)... So, what would be a problem?


>> You need to use the "environment" script that was also created in /tmp to enable a "mcstas 1.12c 

I did run this script right after migration process, and it was fine. So now it's in /usr/local/bin and when I run mcgui after this script in terminal, it starts old gui with new engine:

  Define /Users/emoskvin/.mcstas/hosts

  or use option --machines=<file>

and in my case "run menu" doesn't have parameters list as described above.
So, I'm stacked....

Best, Evgeny.
