I am getting this error (see below) while executing 2D classification: Any ideas on how to fix this?

Does the Linux account that runs CryoSPARC jobs have write access to /cachepool/cryosparc_cache on all the worker nodes?

Don’t know how to set this. If you could direct me it would be helpful.

Hi…I figured it out. The worker node was not on the PATH. Then I had to update it using the connect command where I pointed to the right ssdpath which will have appropriate permissions. Thank you.
