EXI allows to provide information about the samples in a shipment uploading one or more CSV files. This document contains information about the format and contents of the CSV file.
A CSV file is a plain text format mainly used to store tabular data. CSV means Comma-Separated Values then each value is separated with a comma. Example:
Dewar1,MX001,Unipuck,1,HEWL,xtal101,,P43212,77.4,77.4,37.2,90,90,90,,,,,,,,,Lysozyme test crystal
This line describes a Hen Egg White Lysozyme crystal, located in the position 1 of a Unipuck labeled ‘MX001’ included in a parcel called ‘Dewar1’. Optional or unused columns can be left empty, although the separating commas must be present.
Using a file like this makes it easier to edit, update or correct the sample information; the CSV file also acts as a backup. The advantage of using a CSV file and not a Excel file is that CSV is a standard format that can be handled in all different operating systems and it does not depend on any program.
Note: All the fields in the CSV file are case-sensitive
