h2. Extra Package and Installation

|_.program/package|_.notes|

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

{{include(comtypes installer)}}

h3. Run checkcom.py

* From a command line window:

<pre>cd C:\python27\Lib\site-packages\pyscope

C:\python27\python.exe checkcom.py</pre>

* The output sould contain this output

<pre>

Found ESVision.Application done.

</pre>

h2. instruments.cfg

Eagle:

<pre>

[camera]

class: tia.TIA

zplane: 50

height: 4096

width: 4096

</pre>

h2. Setup

* Set camera configuration to give the [[Leginon Image Orientation|standard Leginon orientation]].

h2. Programs to open before Leginon Client: TIA.

h2. Testing with pyscope

In python command

<pre>

form pyscope import tia

g = tia.TIA()

g.setExposureTime(200)

g.getImage()

</pre>

You should get a bunch of numbers in a numpy array.

h2. Trouble shooting

Some version of TIA may give an error of that at the end of it says

<pre>

_ctypes.COMError: (-2147352567, 'Exception occurred.', (u"Camera 'tia' does not exist.''.u'ESVision', None, 0L, 0))

</pre>

This happens because TIA scripting (ESVision) knows the camera by a different name.

The correct name may be in TUI/CCDCamera panel.  Or you can find out from these python commands when the camera in question is active (You can make it active by acquire an image in TIA).

<pre>

from pyscope import tia

t = tia.get_tiaccd()

c = t.ccd.Camera

</pre>

You should get the camera name as the output.

With the name, edit pyscope/tia.py and change in the class TIA,

from

<pre>

    camera_name='tia'

</pre>

to

<pre>

    camera_name='THE NAME YOU FOUND'

</pre>
