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

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

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

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.

h1. The following depends on what instrument is controlled by the computer

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 comtypes if this 32-bit computer is for TIA controlling camera or for a Gatan camera on FEI scope.¶

Program	package web site	local copy of win32 installer
comtypes 0.6.2	http://sourceforge.net/projects/comtypes"	comtypes-0.6.2.win32.exe

Modify comtypes if it is used:¶

This include

• TIA controlling camera
• Gatan camera is controlled by older, 32-bit computer
• JEOL models that uses JEOL COM library.

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.

Remove safearray.pyc in C:\Python2*\Lib\site-packages\comtypes\ if it does not appear to recompile (timestamp of the file change) when you import comtype in python command line

import comtypes

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
Found TEM Scripting
or
Found Tecnai Scripting
done.

initializing TOM Moniker
Found TOMMoniker 1.0 Type Library
done.

.....

The output depends, of course, on what is available on your microscope/camera computer. For FEI scopes, you should find either "Tecnai Scripting" or "TEM Scripting" and "TOM Moniker". For Tietz camera, you should find 'CAMC4 1.0 Type Library'

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

Install SEMCCD as Digital Micrograph plugin (Gatan K2 camera only)¶

Thanks to David Mastronarde for providing his DM plug-in using socket connection

Note: If you have SerialEM installed on the same computer, you don't have to go through this. The same Plugin can be used by both programs and share the same port¶

Remove your older SEMCCDxxxx.dll in C:\Program File\Gatan\Plugins if you had it from prevous leginon-only installtion¶

Download and extract the files¶

1. From your browser, go to [[ https://bio3d.colorado.edu/ftp/SerialEM/FrameAlignment/]]
2. Choose Shrmemframe*..exe for your version of DM to download to your Gatan PC.
3. Run the downloaded file and follow its instructions.

Add a new environment variable SERIALEMCCD_PORT if not exist already from SerialEM installation. Set the value to an unused port between 50000 and 60000 to avoid conflict with other programs. Avoid ports used by Leginon, especially not 55555.

Port 50000 or 50001 usually works.

Install Google protobuf (DE camera only)¶

Protobuf installation instruction¶

Google Protobuf is an open source communication library DE use between client and server. For C++ programs, it is built into the program, so no external library installation is needed. However, for Python/Leginon only, the library will need to be added. A simple way to install this for python use on DE camera computer (Windows) follows:

1. Download 2.3.0 source zip file as well as the win32.zip binary file
2. Unzip both packages.
3. Copy the binary file protoc-2.3.0-win32/proc.exe into protobuf-2.3.0\protobuf-2.3.0\src folder
4. Go into protobuf\python and run "python setup.py install".

Note: If it attempts to install 0.6c9 version of setuptools and failed to obtain the file, download the ez_setup.py file from setuptools for Windows 7 at https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py You can then replace the one in your protobuf-2.3.0/python folder.

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.
