Use Cases Enviro
This page describes the progress of all use cases related to environmental DNA and environmental samples. For all use cases described below we are currently working on stable test examples, that one can follow. If already available we will use real examples to play with.
Environmental sample data are causing trouble regarding proper mapping with ABCD and Darwin Core. The traditional way of a few identifications for a single specimen is not working here. Since the eDNA itself can be stored similar to gDNA, this topic is of interest for GGBN and we must find a solution. Currently a working mapping with ABCDGGBN_Enviro exist. As soon as this works as required, a solution for DwC-A will be created as well.
eDNA from abiotic eSample
This is a simple parent-child relation. The difficult issue is the big amount of taxa resulting from BLAST/sequencing. They should be displayed without confusion. Also one should be able to search for all included taxa without confusion regarding the hitlist.
Stable test example: http://sandbox.ggbn.org/ggbn_sandbox/search/record?unitID=DB+e200000&collectioncode=DNA+Bank&institutioncode=B The raw ABCD file can be retrieved by clicking on the links to the left.
Search for eSamples is now working.
Search for eDNA is also working. This is provided as preparationType, so now one can search for all preparation types (also leaf, muscle, gDNA etc.)
Krona file is now embedded and displayed in the tab "Visualization" right to “Taxon List”.
- Add the Dryad resource for the raw data
- Add Loan information for the enviro sample
- Do the same thing with DwC-A
- Krona file currently provided as sequencing-reference, term does not fit very well yet
gDNA, culture, specimen, abiotic eSample, eDNA
This is a complex parent-child relation. The gDNA points to the culture. The specimen also points to the culture. Both specimen and culture points to the eSample. In addition the eSample is the mother of hundreds of further cultures, specimens, gDNA samples and of course a eDNA sample.
Real example (work in progress): http://sandbox.ggbn.org/ggbn_sandbox/search/record?unitID=DB+8219_D03_030&collectioncode=DNA+Bank&institutioncode=B
eSample from biotic environment
In comparison to the abiotic eSample this one has a main taxon, e.g. the animal or plant which serves as the environment. This makes a difference in search and display.
eDNA or eSample from ancient material
