h2. Make DDD movie stack

The following section comes from Appion Manual

{{include(appion:Direct_Detector_Frame_Processing)}}

h2. Making Gain/Dark correction one image at a time without saving results to databases

Two scripts using Leginon infrastructure to locate references and do gain/dark correction but not involving saving results to the leginon/appion databases are attached here

*correctframes.py* let you correct a range of raw frames in an image and output as mrc file.

*correctstack.py* let you correct each frame in the specified summed image and output at 2D image stack in mrc format.

type:

<pre>

python correctframes.py

</pre>

for the options

h2. Do it yourself

If you want to do everything yourself, you can use the python script

"getReferences.py":http://emg.nysbc.org/projects/leginon/repository/changes/branches/myami-3.1/leginon/getReferences.py

to find the location and filenames of the references and work on them yourself.

*Beware that the fames are often in different orientation from the reference images in Leginon*

If there are no bad pixel/column/row on your camera that you included in your correction plan, you can feed the properly rotated/flipped references to the drift correction program by Xueming Li.
