An unclean slate, discrepancies between food input and recovered protein signal from experimental foodcrusts: SI3 and the experimental foodcrust 3D scans

This dataset contains Supplementary Information 3, the metadata from the MetaMorpheus database search, from the publication "An unclean slate, discrepancies between food input and recovered protein signal from experimental foodcrusts" by Dekker et al. 2025. Additionally, the object files of most of the 3D models of the experimental ceramic vessles, both from before and after the cooking experiment, are also included in this repository. SI_3_MM_metadata.zip contains the task files (.toml) generated by MetaMorpheus detailing the exact settings used for the calibration, G-PTM-D and search task of MetaMorpheus for protein identification. Additionally, the .zip file contains the databases used in task search, namely the full proteomes from Bos taurus, Beta vulgaris, Salmo salar, Spinacia oleracea and Chenopodium quinoa downloaded from UniProt in fasta format on 03-03-2023, as well as the cRAP database of common contaminants downloaded through the MetaMorpheus interface. The remaining zip files each contain the 3D model .obj and texture files of the eceramic vessels used in cooking experiments to create foodcrust. 3D scans were acquired both before and after the cooking experiments in order to show differences in the amount of foodcrust that formed, depending on the contents of the cooked mixture. Unfortunately, 3D models are not available for all of the 21 ceramic vessels used in the cooking experiments, as the original 3D files for some of the vessels have become corrupted. The 3D scans were acquired using an Artec Space Spider (Artec 3D) and model construction and analysis was performed using Artec Studio 16 Professional v16.0.8.2.
