Leginon

h1. Falcon 3 support

h2. Requirement from camera manufacture:

* Krios 2.12 or Talos/Arctica 1.12 software version.

* Advanced TEM Scripting

h2. Required leginon version:

* 3.4 and above

h2. Extra Package and Installation

|_.program/package|_.notes|

|TEMAdvancedScripting.dll |(Should come with the microscope)|

{{include(comtypes installer)}}

{{include(comtypes_installation)}}

You should have

<pre>

TEMAdvancedScripting

</pre>

h2. instruments.cfg

* Falcon3 class is for linear mode and Falcon3EC class is for electron counting mode. You want to have both.

<pre>

[camera]

class: feicam.Falcon3

zplane: 50

height: 4096

width: 4096

</pre>

<pre>

[camera]

class: feicam.Falcon3EC

zplane: 50

height: 4096

width: 4096

</pre>

h2. Setup

* Set dose rate and acquire References using TUI Reference manager.  Don't do it in Leginon.

* Set up in fei.cfg (See FEI scope installation instruction)

<pre>

[camera]

FRAME_SUBPATH = leginonframes

</pre>

In this case, you will need to create a directory called leginonframes on your Falcon image storage server (called OffloadData on your scope PC) with these parent directories

<pre>

OffloadData\TemScripting\BM-Falcon\leginonframes

</pre>

This leginonframes directory can then mounted on your permanent storage system and allow rawtransfer.py to rsync the files.

h2. Programs to open before Leginon Client: TIA.

h2. Testing with pyscope

In python command

<pre>

form pyscope import feicam

g = feicam.Falcon3()

g.setExposureTime(200)

g.getImage()

</pre>

{{include(pyscope_test_result array)}}

h2. Trouble shooting

If TEM Advanced Scripting is not setup correctly by the manufacture, a configuration error will appear similar to this:

<pre>

_ctypes.COMError: (-2147467259, 'Unspecified error.', (u"Could not load Storage Server configuration file: C:\\ProgramData\\FEI||AcquisitionStorageServer||StorageServer.config', u'',u'', 0, None))
