h3. TEM *cs is the coefficient of spherical aberration in meters*. Find out from TEM manufacture the proper value for your tem. For example <pre> [tem] class: tecnai.Tecnai cs: 2.0e-3 </pre> h3. Camera *height and width are number of pixels based on the orientation presented in Leginon image viewer* * 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. For example <pre> [camera] class: gatan.Gatan zplane: 50 height: 4096 width: 4096 </pre> *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. !zplane.png! *HEIGHT and WIDTH are not shown in these examples for simplicity* * One computer for both tem and digital camera: <pre> [tem] class: tecnai.Tecnai cs: 2.0e-3 [camera] class: gatan.Gatan zplane: 50 </pre> * Separate computers for the two instruments: configure only the instrument reside on the particular computer ** On the computer that controls the tem: <pre> [tem] class: tecnai.Tecnai cs: 2.0e-3 </pre> ** On the computer that controls the digital camera: <pre> [camera] class: gatan.Gatan zplane: 50 </pre> * Two camera cameras that retract/insert at the same plane: time, typically one of them is an off-axis camera, such as in the case of DE12 and DE Survey camera pair. {{include(Instrumentcfg_for_DE-12)}} ** On the computer that controls the digital camera: <pre> [camera1] class: de.DE12 zplane: 50 [camera2] class: de.DESurvey zplane: 50 </pre> * Two cameras on the same computer but one is retractable and one is non-retractable and at lower position. ** On the computer that controls the digital camera: <pre> [camera1] class: de.DE12 zplane: 50 [camera2] class: tietz.TietzPXL zplane: 5 </pre> * 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. <pre> [camera1] class: dmsem.GatanK2Base zplane: 50 [camera2] class: dmsem.GatanOrius zplane: 49 </pre>
