Error in ctf global refinement

Hi! I’m getting this error running some dataset. After a refinement, I’m running global ctf refinement and I’m getting this:

[CPU: 835.6 MB]  Traceback (most recent call last):

numpy.linalg.LinAlgError: Singular matrix

Any idea what is going on? Version is latest: 3.2.0. I’m running this through Scipion, which has worked nicely in the past, but will run it within cryosparc to make sure is not an interfacing issue, and post result here.

Dear @pconesa1, thanks for reporting. Please let us know once you have had a chance to run the job directly in cryoSPARC to rule out any Scipion-cryoSPARC interfacing issues. Thanks
