Genemap's ultrasound model is calibrated on what the processor grades: MSA carcase feedback — MSA marble score, AUS-MEAT marble score and, where the plant has one, camera IMF %. Laboratory chemical IMF is kept as an optional gold standard. A model is trusted only once it has been checked on animals it was never trained on, and it is always named after what it was trained on — a model trained on marble scores is a marbling grade, never an IMF %.
Load the MSA feedback file for a kill (CSV or Excel, as downloaded from Livestock Data Link). Each carcase is matched to your animals by NLIS or EID, and the body number is checked against any calibration-kill record. Every row is checked first; if any row is wrong, nothing is imported and the problems are listed. Every column in the file is kept. Marble scores stay as grades — they are never turned into an IMF %. Scanned animals become calibration records (scan-to-kill over 14 days is flagged); unscanned animals are kept as your farm's kill history.
Columns: sample_code, chemical_imf_pct, optional sample_site, lab_ref, notes.
Every row is checked first — unknown sample IDs, duplicates, values out of range, missing sites. If any row is wrong, nothing is imported

From sessions planned as repeatability studies (each animal scanned twice the same day, re-positioned between scans).
