Hi Pranav,
Thanks for the suggestion! I do need to store the TS for realignment during acquisition. But I could include an option to delete it after acquisition is done. Quick and dirty binning should not be an issue. The question is: do you also want an mdoc file written accordingly?
Which of these options would be your preference?
Thanks and best, Fabian
Removing after collection sounds good! Re binning - In my view there are broadly three use cases (a) High res STA of macromolecules (b) Morphological studies of the object (c). Quick look see for determing "good data" In case (a) most users rarely use the assembled tilt-stacks and prefer to perform pre-processing in all the different software packages, for these use cases, there is no benefit in keeping full-res stacks. But unmodified mdocs for the stacks is super critical. In cases (b) and (c) a coarsely binned stack is OK since the level information being seeked is not affected by the high res information (indeed binning may help with contrast).
In both cases i dont think the mdoc file needs to be perturbed and should reflect the data collection params (because loss of this information is irretrievable).
Ok! This is implemented and should come in v1.8.1 soon with a few other small tweaks. I just want to get a bit more testing done before releasing it. Let me know if you want to already give it a try!
Best, Fabian
Now available in v1.8.1. Let me know if you run into any issues! Thanks again for the suggestion!
Best, Fabian
Thanks Fabian!

Hi Pranav,
Okay, to clarify:
Thanks and best, Fabian
Hi Fabian, Below is his response - 1. No, it doesn't happen with the normal target selection but will have to re-test with the latest version. 2. We only use the one from the FIB and we think our pre-tilt values are having correct sign. 3. Yes, it seems to be able to align the target properly.
Thanks, Pranav!
I was reading description of the problem again and do I understand correctly that (A) and (B) are requests for features and not something you already tried?
If so, (B) should be achievable by simply disabling both previewAli and viewAli. Then PACEtomo will only align to the tracking tilt series and only use the relative image shifts from there without aligning to the template.
Another question: Do you collect the montage for target cropping at 0º stage tilt? Or do you try to compensate for the pretilt? Also what is the startTilt you use? PACEtomo assumes target selection at 0º, but if the preview alignment to the template step looked sensible that should not be the issue.
Could you send me a log file of a run where the 1st and 4th image showed a large error?
I haven't tested the targetsFromMontage script on lamellae for a long time. But SPACEtomo is using pretty much the same approach (viewAli only) and I didn't notice such issues. I will try to test the targetsFromMontage script in my next session in a few weeks.
Hi Fabian, Can you write to me at p[dot]shah[dot]lab[at]gmail[dot]com? I am unable to reach you at your tokyo email id.
Hi Fabian, Would you consider adding an option to the PACETomo script, by which a user can define generating smaller ordered TS stacks? I can see that you already have a reordering function, so perhaps binning may also be added? This way, the user can potentially save space on the scope computer. Additionally, could a user also have an option to simply turn off storing the TS? Best, Pranav
