| sample volume or weight for DNA extraction | optional | Volume (ml) or mass (g) of total collected sample processed for dna extraction. note: total sample collected should be entered under the term 'sample size'. (Units: ng) | |
| nucleic acid extraction | optional | A link to a literature reference, electronic resource or a standard operating procedure (sop), that describes the material separation to recover the nucleic acid fraction from a sample | |
| nucleic acid amplification | optional | A link to a literature reference, electronic resource or a standard operating procedure (sop), that describes the enzymatic amplification (pcr, tma, nasba) of specific nucleic acids | |
| library size | optional | Total number of clones in the library prepared for the project | |
| library reads sequenced | optional | Total number of clones sequenced from the library | |
| library vector | optional | Cloning vector type(s) used in construction of libraries | |
| library screening strategy | optional | Specific enrichment or screening methods applied before and/or after creating clone libraries in order to select a specific group of sequences | |
| pcr conditions | optional | Description of reaction conditions and components for pcr in the form of 'initial denaturation:94degc_1.5min; annealing=...' | |
| pcr primers | optional | Pcr primers that were used to amplify the sequence of the targeted gene, locus or subfragment. this field should contain all the primers used for a single pcr reaction if multiple forward or reverse primers are present in a single pcr reaction. the primer sequence should be reported in uppercase letters | |
| adapters | optional | Adapters provide priming sequences for both amplification and sequencing of the sample-library fragments. both adapters should be reported; in uppercase letters | |
| depth | recommended | The vertical distance below local surface, e.g. for sediment or soil samples depth is measured from sediment or soil surface, respectively. depth can be reported as an interval for subsurface samples. (Units: mm) | |
| chemical administration | optional | List of chemical compounds administered to the host or site where sampling occurred, and when (e.g. antibiotics, n fertilizer, air filter); can include multiple compounds. for chemical entities of biological interest ontology (chebi) (v111), please see http://purl.bioontology.org/ontology/chebi |
