System Crashes during live reconstruction

[Hovden]

(1) Load dataset (2) Mark as TiltSer (3) Run WBP and change to update %2 iterations (4) interact with dataset continuously during reconstruction. (5) System crashes.

I am unable to recreate this on Linux. I will now try on OSX. I am assuming that in step 3, you are saying update the python code at line 59 to change 40 to 2? i.e. increasing the update rate?

I am unable to recreate on OSX 10.12.6. Is there some specific interaction that causes the crash? I am adding a volume module and rotating the dataset.

Chris,

I would test on larger datasets ( ca 512 or greater).

When the pinwheel appears, there is a 50/50 it will crash. Typically happens when interacting with high refresh (eg changing 40 to 2).

@Hovden I am using TiltSeries_NanoParticle_doi_10.1021-nl103400a.tif, can I get access to the data set you are using?

[Hovden]

There are several datasets in the Nature Sci Data Article published in 2016, google nanomaterial datasets for tomography hovden.

Also, cancel and delete reconstructions midway to set tomviz up for crashes or glitchy pipeline- it won’t take much.

You can also generate projections from the generate nanoparticles datasets.

I can sit down this afternoon for a skype call to get a patch release out.

I have tried with a couple of other datasets and still can't recreate this crash.

[Hovden]

I have been using: "tiltser_180.tif"

But I can get a crash or an error, ~20% of the time on any reconstruction >256. For example (1) Generate Random Nanoparticles (2) Project Tilt Series (3) Create Volume Render (4) Weighted Back Projection.

Produces the following error:
