Question

Can't complete `dials.symmetry` or `dials.scale` jobs on some Windows machines

Opened this issue a year ago · 7 comments

At the CCP4 workshop in Prague, some users with Windows laptops could not complete dials.symmetry or dials.scale jobs. They would run up to a certain point at which the node would turn red and the job would appear failed.

I have a suspicion it is due to special characters in the log file, in particular the first line where "CC½" is printed for example. Some Windows computers were okay, but many had this problem. It might be related to something like a Czech locale, although that is just a guess.

Something to check for DUI2

I have a Windows 10 virtual machine so I can test and try to reproduce, I have couple of questions:

Will this happen with any dataset? so I can test with the small X4_wide.
Will I need to install Czech locale in my VM?

Thanks,

We were running with the beta lactamase tutorial dataset (https://dials.github.io/documentation/tutorials/processing_in_detail_betalactamase_dui.html)

As for the Czech locale, I'm not sure. I did not have time in the workshop to figure out what the common feature was between the laptops where this failed vs those where it worked.

I've just tested this on my Windows 10 PC, where it worked okay, but what is printed to the log looked odd anyway:

Resolution estimate from CCÂ½ > 0.60: 1.40

I will try installing a Czech locale to see if that makes a difference.

I managed to reproduce this by changing my Windows system locale settings to Czech. I did that in a few places, but I think the critical one is here:

After that, the behaviour looks like this:

DUI-symmetry-log-bug.online-video-cutter.com.mp4

You can see the log gets as far as

Removing 2 Wilson outliers with E^2 >= 16.0

it probably fails on the next line, which contains the $\sigma$ character:

Resolution estimate from <I>/<σ(I)> > 4.0 : 2.09

@luisodls Are you able to check if this is still a problem for DUI2?

Answer 7 · 2023-07-19T18:20:00.000Z

@dagewa I will check as soon as I finish what I am doing now with the dials.split_experiment feature.

I have a couple of Windows 10 virtual machines laying around, I suppose VirtualBox machines will let me reproduce, my bare metal Windows boot broke recently and I had to reformat. I will let you know how it goes.
