Example datasets

In accordance with BBSRC policy on data sharing, many of our datasets which have been collected via publicly funded projects are freely available for further research and analysis. Below is a list of datasets, including concise metadata, ready for download. All datasets are in zipped '.csv' format.

The accompanying citations give full experimental details relating to the original data acquisition. Please use the relevant citation in any publications arising from further analysis of these datasets.

• 120 Mid-infrared (MIR) spectra. Duplicate acquisitions from 60 authenticated extra virgin olive oils from 4 different countries of origin; raw data matrix size [570 x 120]. Obtained using Fourier transform infrared (FTIR) spectroscopy with attenuated total reflectance (ATR) sampling. As described in "FTIR spectroscopy and multivariate analysis can distinguish the geographic origin of extra virgin olive oils". Tapp H.S. et al, J. Agric. Food Chem. 51 (21) 6110-5 (2003) Abstract on Pubmed.
• 214 Lanes of SDS-PAGE data, from 19 Spanish and 18 French dry-cured hams; data matrix size [214 x 431]. Triplicate lanes of duplicate extractions (giving ~6 data vectors per sample), pre-processed and aligned as described in "Sodium dodecyl sulphate-polyacrylamide gel electrophoresis of proteins in dry-cured hams: Data registration and multivariate analysis across multiple gels", Olias R. et. al., Electrophoresis 27 (7) 1288-1299.

• 144 electromyograms (time-varying bioelectrical signals measuring muscle activity; 30seconds sampled at 1kHz; raw data matrix size [30000 x 144]). Obtained using surface electromyography (sEMG) from the Right-Masseter muscle group in 6 volunteers, performing duplicate readings of 4 prescribed chewing movements, on 3 separate occasions. As described in "Electromyographic responses to prescribed mastication" Kemsley E.K. et al, J. Electromyog. & Kinesiol. 13 (2) 197-207 (2003). Abstract on Pubmed. More on our EMG work.
• 56 Mid-infrared (MIR) spectra of authenticated freeze-dried coffee samples (arabica and robusta species, respectively 29 and 27 of each). Raw data matrix size is [286 x 56]. Obtained by Fourier transform infrared (FTIR) spectroscopy with diffuse reflectance (DRIFT) sampling. The data are described in full in the journal paper "Near- and Mid-Infrared Spectroscopies in Food Authentication: Coffee Varietal Identification" Downey G. et al, J. Agric. Food Chem. 45 (11) 4357-4361 (1997). Abstract on ACS
