One of the datasets that I have processed with cryosparc v2 has finished ab-initial reconstruction. However, I was not able to continue with homogeneous refinement job since it kept printing:
“SSD cache : cache waiting for requested files to become unlocked.”
We have already cleaned the cache folder and restarted cryosparc. However, whenever I started a new homogeneous refinement job with this dataset, it still complained like above. Other datasets don’t have this issue.
Is it possible that another job in cryoSPARC is running against the same dataset? Or were using the files as they were deleted? The “status” of the files are kept in a collection inside mongodb. If cryoSPARC has already seen the files, there would be a document inside mongo outlining their “status”. This is why even though the files don’t physically exist in the cache, they can be locked- cryoSPARC didn’t have a chance to update the status of the files, making the application think they’re currently being used.
