Description: Motif DB applicable to lichen samples, produced with 1500 spectra from with 250 lichen molecules. The spectra were produced by three different machines (Agilent 6530 qToF, Waters Xevo G2-XS qToF, Thermo Orbitrap q-Exactive). The chemical classification of lichen compounds as described in Identification of lichen substances (Huneck & Yoshimura, 1996) was used to annotate the motifs produced. MS2LDA experiment used : 200326_LDB_NEG_02.
