@nyhui,
See the above: “Since v3.2.0+210629, particle .mrcs that are imported into cryoSPARC are prepended with the UID of their dataset file in order to keep them unique.”
The second step is to remove the UIDs. You may have different names for “J1, SampelName, Extract/job025”. You should be able to find them from the first star file and particle.star.
If you are using other older versions of cryospac, and there is NO UID in your first star file, the following command (one step) should work:
~/pyem/csparc2star.py cryosparc_P74_J165_004_particles.cs P74_J165_passthrough_particles.cs cryosparc_P74_J165_004_particles.star --copy-micrograph-coordinates particles.star
