Because Metabolonote is a wiki system, it allows the submitters to attach free additional information about the metadata, such as images of the samples, video recordings of tricky analytical procedures, and links to a journal's website where the results are published.
Metadata of the liver and kidney samples used for the microarray analysis including age of rats at the time of death via euthanasia.
There is a link to extensive metadata describing the samples and sample processing on GeneNetwork.
Metadata were available for 8 of the samples containing the deletion; 7 (87.5%) of the 8 were from cases resulting from human-to-human transmission (p = 0.0544, Fisher exact test), suggesting that this deletion might be associated with increased fitness in humans.
When a stock was subjected to any biotic or abiotic treatment prior to phenotypic evaluation, it can be linked to an experiment of type 'sample_treatment' and the metadata and the protocols of the sample treatment experiment can be stored in nd_experimentprop, protocol and protocolprop (see section 1.2).
The main functions of the sample metadata are to give the sample a unit identity and to make it reproducible or at least traceable.
In this way, the exchange of the sample metadata with the respective research collection can include the information about and, optionally, a stable link to existing character datasets, or even the stored character datasets themselves.
The core of the sample metadata is found on labels attached to a collection object, which may be supplemented, in the case of poorly labelled 'historical' specimens, by data from related sources, such as published reports on expeditions and laboratory protocols.
However, the opportunistic nature of the sampling for that study necessitated the inclusion of collections with incomplete metadata or lack of individual trait data.
Metadata includes detailed information about the three-dimensional (including depth, or height) geography and environmental features of the sample, physical data about the sample site, and the methodology of the sampling.
