Hitachi 7800 specific installation¶

Install myami package on the associated camera computer¶

• Instead of installing myami package on HHT scope-controlling PC, the access can be through the computer controlling the digital camera.

• No special supporting package needed.

hht.cfg¶

hht.cfg records some instrument specific parameters that are required to convert the instrument output to SI units that Leginon depends on.

The values in pyscope/jeol.cfg.template is based on NYSBC HT7800 equipped with TVIPS XF416. You may start with these and copy it
to pyscope/hht.cfg or other valid myami configuration file locations.

instruments.cfg¶

[scope]
class: hitachi.HT7800
cs: 3e-3

• Cs for HR and HC modes are 3.0 mm and 5.2 mm, respectively. You will most likely use HR mode on the final image.

• You will also be adding the camera in the same instruments.cfg since this file is located on the camera computer in this instruction.
