CTF processing in 3 stages

To get familiar with how e2ctf.py works, try separating the way you use e2ctf.py into three stages:

Auto fitting

e2ctf.py 1.img --voltage=200 --apix=2 --cs=3.2 --autofit

This runs auto CTF parameter determination, storing the result in a local database.

Fine tuning

e2ctf.py 1.img --gui

Now that you have determined the parameters with the first command, have a look at the results in the interface. Tweak if necessary. Save any changes you make with the Save Parms button

Write output

e2ctf.py 1.img --phaseflip --wiener

Finally generate output. The output will be in the particles directory.

Processing multiple images simultaneously

e2ctf takes multiple images as input, so you can use commands like this:

e2ctf.py *.img --voltage=200 --apix=2 --cs=3.2 --autofit
e2ctf.py *.img --gui
e2ctf.py *.img --phaseflip --wiener

Combining stages into a single command

You can combine more than one of the e2ctf processing stages into a single command. For instance you can run automated fitting and open the GUI with a single command like this:

e2ctf.py 1.img --voltage=200 --apix=2 --cs=3.2 --autofit --gui
e2ctf.py *.img --voltage=200 --apix=2 --cs=3.2 --autofit --gui
