| Project Title: | Combinatorial metabolic mixtures for encoding abstract digital data |
| Project Type: | FTICR-MS acquisition of 1536-spot MALDI plates, comprising thousands of mixtures of common metabolites |
| Project Summary: | This data comprises FT-ICR MS readouts of 1536-spot MALDI plates. Each spectra is a measure of a specific metabolic mixture from a library of 36 common metabolites. The combinatorial mixtures of metabolites are used to encode abstract digital data (images). A comprehensive list of the metabolites and specific mixture present in each spot on each plate are provided in metadata files. Data is provided in open-source .hdf5 files. |

| Treatment ID: | TR001254 |
| Treatment Summary: | Combinatorial mixtures of metabolites were deposited using a Labcyte Echo 550 on to a MALDI steel plate at 30-60 nL volumes. Aminoacridine matrix was added in the ratio 0.7:1 to 1:.7 to metabolite concentrations. The spot droplets were air dried. No further treatments were performed prior to data acquisition. |
