xmipp_ctf_correct_idr (v3.0)

Usage

Correct CTF by using IDR This utility allows you to make reconstructions removing the effect of the CTF. The projection images are modified according to a current guess of the reconstruction and the CTF definition. The modified images should be used for reconstruction which now serves as a new current guess for a new IDR iteration. The method is fully described at http://www.ncbi.nlm.nih.gov/pubmed/15005161

The program will assume that the image phase have already been corrected (otherwise the initial solution is too far from the true solution and the algorithm does not converge).

Parameters

-i, --input <input_file>
Metadata with images and corresponding CTFs (ctfdat)
--mode <mode=overwrite>
Metadata writing mode.
where <mode> can be:
  • overwrite Replace the content of the file with the Metadata
  • append Write the Metadata as a new block, removing the old one
-o, --output <output_file=>
Output file: metadata, stack, volume or image.
--oroot <root=>
Rootname of output individual images. Output image format can be set adding extension after rootname as ":ext".
--vol <volume>
Volume with the current reconstruction
--mu <s=1.8>
Relaxation factor
