| Qualifier | specimen_voucher |
| Definition | identifier for the specimen from which the nucleic acid sequenced was obtained |
| Value Format | /specimen_voucher="[<institution-code>:[<collection-code>:]]<specimen_id>" |
| Example | /specimen_voucher="UAM:Mamm:52179" /specimen_voucher="AMCC:101706" /specimen_voucher="USNM:field series 8798" /specimen_voucher="personal:Dan Janzen:99-SRNP-2003" /specimen_voucher="99-SRNP-2003" |
| Comment | the /specimen_voucher qualifier is intended to annotate a reference to the physical specimen that remains after the sequence has been obtained; if the specimen was destroyed in the process of sequencing, electronic images (e-vouchers) are an adequate substitute for a physical voucher specimen; ideally the specimens will be deposited in a curated museum, herbarium, or frozen tissue collection, but often they will remain in a personal or laboratory collection for some time before they are deposited in a curated collection; there are three forms of specimen_voucher qualifiers; if the text of the qualifier includes one or more colons it is a 'structured voucher'; structured vouchers include institution-codes (and optional collection-codes) taken from a controlled vocabulary maintained by the INSDC that denotes the museum or herbarium collection where the specimen resides; Please also visit: http://www.insdc.org/controlled-vocabulary-specimenvoucher-qualifier |
