The conclusion that should be emphasized, based on the results obtained, is that pEDXRF spectrometry when used in investigation of the origin of ceramic artefacts can provide viable results by carefully selecting the experimental conditions and well-thought-out procedure of data processing.
The logistic functioning of the procedure was also tested with a pilot study, which was organized in Cadiz (children) and Madrid (adolescents), to check every step of the procedure, from sampling to data processing.
The required detailed description of experimental procedures and data processing together with storage of raw as well as processed data is essential for thorough follow-up analysis.
The three presented methods (currently still quite unconventional) are characterized by different field procedures and data processing.
For details of sampling regime, laboratory procedures and data processing see Wolf et al. 2010 [ 44].
Data management has been carried out in parallel with data collection, based on standardized and partly automated procedures for data processing and plausibility checking.
Procedures for data processing have been previously described [ 30], including background subtraction, correction for illumination energy, correction for system throughput, and (for reflectance data) calculation of the ratio of tissue reflectance to the reflectance of a white Teflon standard.
Furthermore, heterogeneity in quality of microarray annotation, definition of candidate region limits, and statistical procedures for data processing and differential expression testing limit our ability to investigate the specific causes of enrichment for pQTL candidates in their results.
Certificate programs are likely to provide information about procedures, medical data processing and coordination duties.
Our methodology to detect circadian rhythms in gene expression profiles consists of three procedures: data pre-processing, period detection and harmonic regression modeling (Fig. 1A).
