Thumbnail pictures gone after update to v2.2

Hi there,

I just updated to the latest version. And I noticed that all the thumbnail figures are gone for my old jobs. And for new jobs, the location of the thumbnail figures cannot be found. Could you let me know what causes this problem and how to fix it? Thanks!


Hi Wei,

Are there any errors in the database logs (cryosparcm log database)? If the update completed successfully this should not be the case.

HI Suhail,

I didn’t see any error in the database logs. But when I restarted cryosparc v2, I noticed this error:

Starting cryoSPARC System master process…
CryoSPARC is not already running.
database: started
command_core: ERROR (spawn error)
cryosparc command core startup complete.
command_vis: ERROR (spawn error)
command_proxy: ERROR (spawn error)
webapp: started

The actual jobs seem to run properly. The status shows that I am in v2.2, but the new functions do not show up in the job list. Maybe something went wrong during update?


Hi @wxh180,

It is possible that after the update, previous running processes of cryoSPARC have been orphaned. You might need to find all running instances of cryoSPARC and manually kill them. Try the following:

cryosparcm stop
ps aux | grep superv
kill PID #kill only processes related to cryoSPARC 2
cryosparcm start

Thanks, Suhai! This fixed the problem.
