Labels with digital codes are a basic tool in the tracking of genetic materials.
Among the general content criteria it is established that the labels must:
Among the general design criteria is established:
Corresponding to task a) a design based on four quadratic blocks was defined. Each block corresponds to one of the listed criteria. Based on the available label models, it was also established that a maximum of four fields are available per block. In more detail:
Main collection code
QR Block: Contains all data printed in encrypted form
Option for a next version: include important documentation data as in the case of labeling herbaria. It may include descriptions of the place of collecta and other observations.
Standardized minimum information block. Here you can include four fields. The main idea is that they will be common among collections as
origin of material (collection, crossing, country, ...)
Additional information block. Main idea is to provide important logistical information. It could be included for example:
It was confirmed that the four blocks can be organized in the form of a 2x2 table in quadratic and semi-rectangular labels, maintaining a readability and an attractive visual design. In rectangular profiles such as field ties you can organize the blocks in the form of a row with four columns (1x4) or in a column with four rows (4x1).
An algorithm was implemented in R to generate samples for three different sizes of labels. The algorithm mainly accepts a table with the incoming data, header data, and the name of a template file. The incoming table must have four to eight fields per genetic material. The three header data are configurable at the batch level (ie they are repeated on each label) for the ID block. It is assumed that the authority or the logo does not change and this parameter is only configurable at the template level. The template defines several more specific details such as:
Four samples have been created with some sample data invented for eleven materials in three collections.
