h1. Test run operation problems * [[Test_run_operation_problems#Python-and-Leginon-windows-do-not-stay-opened-on-Windows-PC|When Leginon or Leginon Client is launched,Python window opens and closes instantaneously on Windows]] * [[Test_run_operation_problems#Missing-modules|ImportError "No module named xxxx"]] * [[Test_run_operation_problems#Tecnai-does-not-show-up-in-instrument-list|Microscope or CCDCamera name does not show up in the Leginon instrument list in Instrument Node]] * [[Test_run_operation_problems#Tecnai-does-not-show-up-in-instrument-list|The Microscope computer where Leginon Client runs does not show up in the Launcher list of Leginon when opening an application]] * [[Test_run_operation_problems#Magnification-list-not-in-the-database|No Magnification saved for xxx(your scope)]] * [[Test_run_operation_problems#Leginon-fails-to-aquire-and-save-larger-images|Leginon fails to collect 4kx4k images]] h2. Python and Leginon windows do not stay opened on Windows PC *_Why:_* * Windows closes the python process window because an error is detected. *_Testing: Start Leginon from a python command window so that the error message can be read_* * Follow the following menu to open a python command window: Windows/Start Menu/All Programs/Python2.5/Python (command line) * Python> import start * Read the error message. Copy it to your bug report when asking NRAMM for help. h2. Missing modules *_Why:_* * Either the python path is not set up correctly or the module was not installed properly. *_Testing:_* * script: <link linkend="inst_syscheck">syscheck.py</link> If the missing module is not installed under one of the Python module search path found in the syscheck output, it need to be moved. h2. "Tecnai" does not show up in instrument list *_Why:_* * An error is detected when the instrument is loaded. *_Testing: Import the module in pyScope package through a python command window so that the error message can be read*_ * Follow the following menu to open a python command window: Windows/Start Menu/All Programs/Python2.5/Python (command line) * * Follow instruction in pyScope Bulletin Board Thread "Testing ""Testing if pyScope is working with your TEM or CCD":http://emg.nysbc.org/bb/viewtopic.php?t=246 CCD"":http://emg.nysbc.org/bb/viewtopic.php?t=246 . For example, if "Tecnai" is missing from the instrument list, try this:<pre>Python>from pyScope import tecnai Python>myscope = tecnai.Tecnai() Python>myscope.getMagnification()</pre> * Read the error message. Copy it to your bug report when asking for help. h2. Magnification list not in the database *_Why:_* first time the TEM is used by leginon and the database, the valid magnification for the instrument needs to be saved in the database. Solution: On the scope: Leginon/Instrument> select the microscope to display parameters and click "Get Magnification" button (The icon is of a calculator) on the tool bar. h2. Leginon fails to aquire and save larger images *_Why:_* * Your computer does not have sufficient memory to acquire and correct the large 4kx4k images. Solution: Put on your computer more memory and more memory swap space. * If you file storage system is not on the same computer, there may be problem transfering large data file. This is known to happen from a Windows machine to disk storage operated under Linux through Samba. Solution: Let us know if you have one. h2. Leginon fails to move the goniometer after a new installation or update of pyScope *_Why:_* * tecnaicom.py, the python wrapper of Tecnai Scripting library, has not been created in the running pyScope folder on the microscope controlling computer. Solution: Double click updatecom.py to run it in the (installed) pyScope folder. ______ [[Administration Tool problems|< Administration Tool problems]] | [[Network problems|Network problems >]] ______
