Leginon

h1. Manual Acquisition

Manual Acquisition is a node that allows the electron microscopist to acquire CCD images

manually while at the microscope. This node essentially creates a button to acquire images

manually with Leginon and gives all the benefits of the Leginon database and image storage.

Required bindings: None

h2.  Toolbar

*  Settings = Adjust the manual image acquisition parameters.

*  Grids = Select the current grid.(Not used without Project Database)

*  Acquire = Acquire a current image.

*  Continuous Acquire = Click this to begin acquiring images continuously.

*  Abort = Stop the Continuous Acquire function.

h2.  Settings

*  Camera Configuration = Select the parameters that describe how the image is

acquired.

- Dimension = image x,y pixel dimension

- Offset = x,y offset from top left corner of full CCD image

- Binning = x,y image binning

- pre-configured image sizes

- Custom = customize image dimension, offset, and binning

- Exposure time (ms) = CCD and specimen expsosure time

*  Correct image = When enabled, the raw CCD image will be corrected with Bright and

Dark CCD reference images

*  Save image to database = When enabled, the acquired CCD image will be

automatically stored in the database. All microscope and camera information will be

stored for each image.

*  Loop pause "30" seconds = The amount of time the Continuous Acquire function

waits before acquiring the next image.

*  Label = Enter a label to be inserted in the image file name (in addition to the

normal Leginon file name).*

*  Main Screen: Up before acquire = When enabled, Leginon will raise the

microscope's main viewing screen.

*  Main Screen: Down after acquire = When enabled, Leginon will lower the

microscope's main viewing screen after an image has been acquired.

*  Low Dose:

- Use low dose = When enabled, Leginon will switch the microscope from focus to

exposure mode of the Low Dose kit to acquire the image and then return to focus

mode.

- Low Dose pause "4" seconds = Wait this amount of time before acquiring an image

when using Low Dose on the microscope and acquiring images with the Acquire feature in

this node. Increase the time if the microscope does not change modes fast

enough.
