Dear all,
we have recently encountered a problem where CryoSPARC seems to request too much space on our local SSD and therefore fails to run unless we disable SSD-caching. In the latter case, the job runs fine but takes forever.
We know there is enough space on the SSD and we know that we could run refinement jobs with an order of magnitude more particles just fine. In this particular case we tried to do a homogeneous refinement with only 14788 particles (600x600 pixels) and if I interpret the error correctly, CryoSPARC requests 1.7TB of space. Here is the error message:
