Hi Pranav, Those errors tend to come up arbitrarily, they indicate something has gone wrong somewhere but don't really say where. I noticed you're only trying to reconstruct one tomogram as per your job submission, can you empty the Tomogram Name field and see what happens?
Can you also run a CTF Estimation job using the aligned_tilt_series.star as the input and use the output from the CTF estimation job as the input for Reconstruct Tomograms? I can see there's no CTFFIND output info in the tilt series star file which may be messing with things (it adds more columns than just DefocusU/V)
Hi Euan, I am re-estimating the TS ctf params using CTFfind and will report back. But to add more context to the original post, I was following the pipeline (Import > MotionCorr > CtfFind > Align > Recons). I then went down the rabbit hole of futzing with a test TS star file....
Ok that worked! So perhaps the AlignTiltSeries job type should be moved to in the third position? The current pipeline implies a workflow that is not congruent with the underlying processing pipeline?
Ok. So now that I have reconstructed the tomograms in Relion, they appear to be way worse than the ones AreTomo outputs. Am I failing to turn on some kind of flag by any chance?
(Left Relion, Right AreTomo)
Do you think this is because the pre-tilt has not been corrected during TS alignments (So far I have be running everything with default options)? or is there some kind of rotation; X-Y shift convention that is not being respected during imports?
So you should do CTFFind before Align, so the job order is correct. For whatever reason, the output of CTFFIND wasn't contained in your star file used as input to align tilt series most likely.
The other stuff is weird: usually I consistently find that the RELION tomos looks better than the AreTomo ones so I don't quite get that. It's quite hard to judge without direct access to the jobs and stars. Let me think about it a bit 😬
Is that AreTomo rec from the AlignTiltSeries/job[whatever]/external directory?
Also can you post the note.txt from the AlignTiltSeries job plz? And if you've run AreTomo externally to generate that AT rec, what settings you used in AT?
I have aligned tilt-series using relion's python wrappers for AreTomo and now I wish to generate CTF corrected tomograms. However, ReconstructTomograms fails to run because it is unable to find the rlnDefocusU column in the tiltseries star file.
The input star file for one of the tilt-series is as follows -
I then modified the starfiles the DefocusU and DefocusV columns from the starfile generated after CtfFind. See below, for contents of modified star file -
However, using this star file as an input for reconstruction results in the following error message -
I am running the reconstruct command with the following parameters and the git commit id for this version of relion is

.Would really appreciate inputs on where things are going wrong as I am keen to get Relion tomo working in my hands.
