Factor-aware cross-modal mapping of GC-MS and FTIR resolves geographic and stalk-position contributions to volatile–matrix covariation in tobacco leaves from China

Deguo Li, Weican Chen, Chi Ma, Yang Gao, Hui Chen, Ren Zhang

Factor-aware cross-modal analysis showed that pooled GCMS-FTIR associations were largely geography-structured, highlighting the need to distinguish source-driven covariance from intrinsic chemical coupling. Image created with the assistance of FigureLabs.
