Description

Running on the same image attached #3436 (200 kV, Cs=2 mm, apix=1.47 A)

I tried these parameters as well as the faster --numstep=50. Got the same problem below.

ctfestimate.py --runname=ctffindrun6 --rundir=/emg/data00/appion/acheng/15aug25g/ctf/ctffindrun6 --limit=1 --commit --preset=en-a --projectid=5 --session=15aug25g --no-rejects --no-wait --continue --ampcarbon=0.15 --ampice=0.07 --fieldsize=512 --medium=carbon --bin=2 --resmin=30 --resmax=4 --defstep=1000 --numstep=50 --dast=500 --expid=605 --jobtype=ctfestimate

ctf estimation is used all the time. If the new change in the background fitting is causing this much trouble, should we revert and make it more as an option for now ?
