Windows Installation¶

• You need to repeat installation of the general packages for each of the computer involved in Leginon operation with addition for the camera and scope.

Add the IP address and matching hostname of the microscope and digital camera computer in your host file on the main Leginon computer, and vice versa.¶

Find out what python thinks the hostname is with python command line. REPEAT this both on Linux and Windows PC¶

Run the following in python command line:

import socket
socket.gethostname()

Find out the ip address associated with the hostname¶

Run the following in python command line:

import socket
socket.gethostbyname('your_host_name')

Modify your "hosts" file on the linux Leginon computer to include the instrument hosts if the latter is not already mapped by your domain name server¶

• On Linux, this "hosts" file is at

/etc/hosts

Example of a "hosts" file:

192.000.1.222   instrument_host_name.domain_name instrument_short_host_name

Use shorter linux hostname if desired¶

If you'd like to shorten your linux hostname recognized by socket without the domain name, you may do so as root

hostname your_shorter_hostname

and also add that to the /etc/hosts as an alternative name

192.000.1.333   long_host_name.domain_name your_shorter_hostname

You will need to restart networking to make it persistent.

/etc/init.d/network restart

Test the change by finding the ip address with the hostname as in the above section.

The Linux main Leginon computer also needs to identify itself by its hostname registered on the instrument Windows computer.¶

• On Window XP and WIndows 7 this host file is

C:\\WINDOWS\system32\drivers\etc\hosts

• On Window NT, this host file is

C:\\WINNT\system32\drivers\etc\hosts

Register TecnaiCCD.dll (Gatan 32-bit DM on FEI microscope), CAMC4.exe (For Tietz camera), and adaexp.exe (For film exposure)¶

• From the command prompt, run the following commands. You may need to enter the full path of the exe or dll:
  

  adaexp.exe /regserver
  CAMC4.exe /regserver
  REGSVR32 TecnaiCCD.dll

Install Python and supporting packages with their installers¶

Program	package web site	local copy of win32 installer	local copy of amd64 installer
Python > 2.7.10	http://www.python.org	python-2.7.16.msi	python-2.7.18.amd64.msi
wxPython 2.8 or newer	http://www.wxpython.org	wxPython2.8-win32-unicode-2.8.12.1-py27.exe	wxPython2.8-win64-unicode-2.8.12.1-py27.exe
MySQL Python client 1.2 or newer	http://sourceforge.net/projects/mysql-python	MySQL-python-1.2.4b4.win32-py2.7.exe	MySQL-python-1.2.3.win-amd64-py2.7.exe
Python Imaging Library (PIL) 1.1.4 or newer	http://www.pythonware.com/products/pil/	PIL-1.1.7.win32-py2.7.exe	PIL-fork-1.1.7.win-amd64-py2.7.exe
NumPy	(use only from our file to match compiled numextension	numpy-1.7.0-win32-python2.7.exe	numpy-MKL-1.6.2.win-amd64-py2.7.exe
SciPy 0.5.1 or newer	http://www.scipy.org	scipy-0.11.0-win32-superpack-python2.7.exe	scipy-0.11.0.win-amd64-py2.7.exe

Use pyMySQL for leginon 3.6 and above instead of MySQL Python client for both win32 and 64.

pyMySQL 0.10.1 (not higher)

https://pypi.org/project/PyMySQL/

pyMySQL-0.10.1-py2.py3-none-any.whl

Excute the installer files and follow the instructions.

Install the Windows Installer Files from created from source by NRAMM¶

Package	win32	amd64
numextension	numextension-svn.win32-py2.7-numpy1.7.0.exe	numextension-svn.win-amd64-py2.7-numpy1.6.2.exe

Execute the installer files and follow the instructions.

Install the packages you downloaded from NRAMM svn repository¶

The svn checkout is a folder containing several subpackages. You will install the python packages using python installer

These are the sub-packages¶

Name:	Purpose:
leginon	modular TEM image acquisition
pyami	general functions
sinedon	database interaction
pyscope	microscope control and monitoring
imageviewer	image viewing for tomography

If you recall Linux processing server installation instruction, this is a bit different. Numextension and LibCV are not included. Numextension is already installed with windows installer. libcv is not required by Leginon client that this part installation is aimed for.

• Start a command line Window from Start Menu

• Install the package in each folder with commands such as
  

  cd path_to\myami-VERSION\myami\leginon
  c:\\python27\python.exe setup.py install

  
  Then continue with the other packages, replacing leginon with the package name. See "These are the sub-packages of myami that you will install with the python installer." section above for complete list.

Modify comtypes if TIA controlling camera is used or Gatan camera is controlled by older, 32-bit computer.¶

IMPORTANT: After installing comtypes, you must make one modification to it. The module "safearray.py" that comes with comtypes must be replaced with a modified version that we provide. You can find the custom version of safearray.py in the pyscope package. Please copy this module from pyscope into the installed comtypes folder: C:\Python2*\Lib\site-packages\comtypes\. It should replace the safearray.py that is included in comtypes.

TIA controlling camera only:¶

(Reported by a user as a necessary step on his system. May not be necessary) Copy TecnaiCCD.dll and stdscript.dll into pyscope folder

Run updatecom.py¶

From a command line window:

cd C:\python27\Lib\Site-Packages\pyScope
C:\python27\python.exe updatecom.py

The python window appears should say show the required type libraries it found:

Generating .py files from type libraries...
initializing TEM Scripting Error, cannot find typelib for "TEM Scripting" 
initializing Tecnai Scripting done.
initializing TOM Moniker done.
initializing Tecnai Low Dose Kit done.
initializing Tecnai Exposure Adaptor done.

initializing Tietz CCD Camera done.

The output is of course depending on what is available on your microscope computer. You should have either "Tecnai Scripting" or the pairing of "TEM Scripting" and "TOM Moniker".

You will only find Tecnai Exposure Adaptor (Scripting for film exposure) if you ask FEI for it.

The script should generate a few files in C:\\python27\Lib\win32com\gen_py with seemly scrambled names such as BC0A2B03-19FF-11D3-AE00-00A024CBA50Cx0x1x9.py

Register the Tietz ping callback function (Tietz camera only)¶

• From a command line window:

cd C:\python27\Lib\Site-Packages\pyscope
C:\python27\python.exe tietzping.py

camc.ini setup (Tietz camera only)¶

CAMC4 has its own configuration file "CAMC.ini" that will normally be set up already, but you can search for it on your computer and confirm that everything looks right. It will have configuration parameters for several cameras and only one of them will be activated. The only parameter that may need some adjustment is the readout geometry, which affects the rotation and mirror of the image.
