V4.4 Live issues with custom parameters

CryoSPARC Live
1

Hi,

I have recently been using Live in v4.4 and have encountered a couple of issues:

  • I like the new approach to setting custom parameters for 2D and ab initio directly in Live - much better than the old way in 3.x! However, when I restart a job that has been run with custom parameters, the parameters revert to defaults, and when I edit custom parameters for a job that has already been run with custom parameters, the parameters also revert to defaults - I think they should be persistent.
  • If I try to restart a 2D job in “waiting” state with custom parameters, but do not alter the number of classes, it doesn’t use the custom parameters - it just continues streaming classification using the old parameters. Changing the number of classes forces it to restart from scratch.
  • If I add an exposure group mid way through a Live run (let’s say a different grid name, so different search pattern), 2D classification fails with an error (attached below). As it is not possible to edit an existing exposure group, it seems the only way to deal with this is to clear the session and start from scratch.

Cheers
Oli

Hi @olibclarke, thank you for a suggestions! We’ve made a note of these and aim to include them in a future release with several other Live-related improvements.
