Error in Live: 'get_individual_data_mic' request failed

I am getting an error message “Vis request failed when requesting get_individual_data_mic (Error: Internal server error [500])” after motion-correction and ctf completes processing a exposure. It re-appears when selecting any other exposures too.

Also no image appears in the 2D display field.

Everything about the processing seems to be functioning correctly and works with images from another microscope.

My suspicions are the images are oriented with a longer vertical height then horizontal width leaving the images to appear taller than wider, but that is mostly a guess.

I am running cryosparc live v2.14.1

Hi @Paul,

Can you please paste the output of the following log:

cryosparcm log command_vis


Here is the message from command_vis Log that is genereated when I click on an exposure and the error mesages pops up.

Is it possible if you can send us the dimensions (frame size) of your movies?

Thank you for your help @Paul,

We’ve identified this is indeed a bug. It never revealed itself since the code still works in all situations where the micrograph is longer in x than it is in y. I’ll be releasing the fix for this bug in the next version of cryoSPARC Live.
Thanks for your help!

Thank you the notice. I will consider this issue resolved and look forward to the update.
