1 | 1 | Anchi Cheng | *cs is the coefficient of spherical aberration in meters*. Find out from TEM manufacture the proper value for your tem. |
---|---|---|---|
2 | 11 | Anchi Cheng | For example |
3 | <pre> |
||
4 | [tem] |
||
5 | class: tecnai.Tecnai |
||
6 | cs: 2.0e-3 |
||

9 | 10 | Anchi Cheng | * height and width is based on the orientation presented in Leginon image viewer. |
10 | * Some Tietz camera may have an odd physical dimension. Use TCL/EMMenu program to find out the good dimension used in Tietz's own software and entered in this configuration. |

12 | 11 | Anchi Cheng | For example |
13 | <pre> |
||
14 | [camera] |
||
15 | class: gatan.Gatan |
||
16 | zplane: 50 |
||
17 | height: 4096 |
||
18 | width: 4096 |
||
19 | </pre> |
||
20 | |||
21 | |||
22 | 6 | Anchi Cheng | *zplane is a number that gives the order of camera*. If a camera with low zplane value is going to acquire an image, Leginon will attempt to retract all cameras at higher zplane values. |

27 | 1 | Anchi Cheng | * One computer for both tem and digital camera: |
28 | <pre> |
||
29 | [tem] |
||
30 | class: tecnai.Tecnai |
||
31 | cs: 2.0e-3 |
||
32 | [camera] |
||
33 | class: gatan.Gatan |
||
34 | 9 | Anchi Cheng | zplane: 50 |
35 | 1 | Anchi Cheng | </pre> |
36 | |||
37 | 5 | Anchi Cheng | * Separate computers for the two instruments: configure only the instrument reside on the particular computer |
38 | 1 | Anchi Cheng | ** On the computer that controls the tem: |
39 | <pre> |
||
40 | [tem] |
||
41 | class: tecnai.Tecnai |
||
42 | cs: 2.0e-3 |
||
43 | </pre> |
||
44 | ** On the computer that controls the digital camera: |
||
45 | <pre> |
||
46 | [camera] |
||
47 | class: gatan.Gatan |
||
48 | 9 | Anchi Cheng | zplane: 50 |
49 | 2 | Anchi Cheng | </pre> |
50 | |||
51 | 8 | Anchi Cheng | * Two cameras that retract/insert at the same time, typically one of them is an off-axis camera, such as in the case of DE12 and DE Survey camera pair. |
52 | 2 | Anchi Cheng | ** On the computer that controls the digital camera: |
53 | <pre> |
||
54 | [camera1] |
||
55 | 4 | Jim Pulokas | class: de.DE12 |
56 | 9 | Anchi Cheng | zplane: 50 |
57 | 11 | Anchi Cheng | |
58 | 3 | Anchi Cheng | [camera2] |
59 | 4 | Jim Pulokas | class: de.DESurvey |
60 | 9 | Anchi Cheng | zplane: 50 |
61 | 2 | Anchi Cheng | </pre> |
62 | |||
63 | 8 | Anchi Cheng | * Two cameras on the same computer but one is retractable and one is non-retractable and at lower position. |
64 | 2 | Anchi Cheng | ** On the computer that controls the digital camera: |
65 | <pre> |
||
66 | [camera1] |
||
67 | 4 | Jim Pulokas | class: de.DE12 |
68 | 9 | Anchi Cheng | zplane: 50 |

70 | 2 | Anchi Cheng | [camera2] |
71 | 1 | Anchi Cheng | class: tietz.TietzPXL |
72 | 9 | Anchi Cheng | zplane: 5 |
73 | 5 | Anchi Cheng | </pre> |
74 | |||
75 | * Gatan Orius camera that is installed typically with Gatan K2/Falcon camera is technically on the same plane but is not capable of insertion unless K2 is retracted. On the other hand, K2 camera insertion includes a retraction of Orius at lower level of the function call in DM. Therefore, Orius is considered as a camera at lower zplane. |
