-UltraMS spectrum encoder after pretraining and RT/ion-mode adaptation. Use it to obtain a general representation of an MS/MS spectrum.
+Use this model to obtain a general embedding of an MS/MS spectrum.
 
-- **Input:** fragment `m/z` and intensity arrays, plus precursor `m/z`.
-- **Output:** a spectrum embedding (`embedding.embedding`); the `ultrams` package also exposes CLS, peak-weighted, and fused embeddings.
-- **Load:** `pip install "ultrams[hub]"`; `UltraMS.from_hub("dsadd4/UltraMS-RT-only")`.
-- **Source checkpoint:** `Light_ultra/train/output/phase2_rt_only/stage_d_epoch_11.pt`.
-- **Expected source SHA256:** `6a4c6660999848c409303119f6caa54fbae9444d0b75c7fcd8bafd303cde9830`.
