Samples

Source reference

source_reference

Legacy names

individual reference

Source reference is a unique identifier assigned first by the compiler and then by the IsoArcH database to each collected source. In each dataset, these numbers will span from 1 to n, with n representing the maximum number of sources compiled. Once in the IsoArcH database, this identifier will include the dataset number as a prefix. GRIST may automatically populate this field. Example: 1

Sample reference

sample_reference

Sample reference is a unique identifier assigned first by the compiler and then by the IsoArcH database to each collected sample. In each dataset, these numbers will span from 1 to n, with n representing the maximum number of samples compiled. Once in the IsoArcH database, this identifier will include the dataset number as a prefix. GRIST may automatically populate this field. Example: 1
