Hi,
Perhaps something adapted from either this post or this post? Unfortunately, cryoSPARC does not support star file input for micrograph import.
Alternatively, starting from EPU_group_AFIS.py output, you could also collate softlinks to the micrographs and systematically rename them to include the opticsGroup index either prior to initial import, or for the purpose of particle reassignment. This will facilitate ease of string_split/slice in Exposure Group Utilities. See @kookjookeem’s recent post for an examplar workflow.
Cheers,
Yang
