Leginon

h1. JEOL installation specifics

These implementations have pyscope modules included in our repository

h2. JEOL 1230

Developed at New York Structure Biology Center

Please contact David Stokes

h2. JEOL 1400 and 3200 (and other scopes with JEOL's COM library)

Developed originally at Northwestern University by Christian Suloway

h3. Install 32-bit version of myami package on the associated camera computer

* Instead of installing myami package on JEOL scope-controlling PC, the access to JEOLCOM usually work through the computer controlling the digital camera, regardless of the camera manufacturer.

* In addition, probably because of the way JEOLCOM works, the installation is limited to 32-bit version.

h3. Alternatively, install myami package on JEOL scope-controlling microscope

* This is only possible if this PC has TEMExternal3 installed and if it is on the same secured network as Leginon processing and database server.

See [[JEOL External3 setup]]

Please check [[Windows_Installation_All]] for important installation instruction regarding comtypes

Notes from the developer:

<pre>

There are a few conversion factor at the top of the file that may need adjustment depending on the microscope.

</pre>

h2. jeol.cfg

jeol.cfg records some instrument specific parameters that are required to convert the COM output to SI units that Leginon depends on as well as standard focus values needed for initializing defocus reference.

See [[Setup and Calibration for jeol.cfg]]

h2. instruments.cfg

[scope]

class: jeolcom.Jeol

cs: 4.1e-3

h2. Testing with pyscope

In python command

<pre>

from pyscope import jeolcom

t =jeolcom.Jeol()

t.getMagnification()

</pre>

You should get the current magnification at the microscope when the main viewing screen is up

h2. Leginon Calibration specifics

* Image Shift should be calibrated at smaller shift distance if the beam moves too much to affect correlation.
