Direct Detector Frame Processing¶

This section enables the user to create gain/dark corrected frame stack in mrc format from raw movie frames generated by direct detectors such as Direct Electron DE-12 and Gatan K2 Summit.

Gain/Dark Correction of movie frames¶

1. GainDark correction of the raw frame with or without drift correction: Frames obtained from DD are yet corrected for variation of pixel response. In the case of analog detection such as those performed by DE series and K2 Linear mode, they are also not dark corrected. This process performs these correction. Also, it can be followed by frame alignment.

1. Catch up DD frame alignment: Using defergpu option in makeDDRawFrameStack when aligning, the gain/dark correction and alignment are broken up for more efficient use of gpu-capable host. In such a case, this process is launched.
