Example resultHow it works
Normalize positive integer group IDs and retain every candidate optics row. Resolve only unique matches. Keep data and optics fields in separate namespaces, preserve observation count and report unused IDs and name collisions.
Group 2 resolves to the second optics row; group 7 resolves to the first. Group 9 is unused. Row order and group names do not replace numeric keys.
Limits
RELION 3.1+ row-oriented loop subset: up to 2000 optics rows, 20000 observations and 200000 parsed fields. Tabs/ASCII space runs collapse as in maintained preprocessing, even inside quotes; raw lines remain. Wrapped/scalar/multiline and embedded matching-quote forms are excluded. No image/file checks, physical acquisition verdict, full STAR validation, merge or repair.
