= Updating to MeLuDI 1.2.1 = Updating to MeLuDI 1.2.1 requires some manual changes to the items that already exist. This is due to the decision to change storing names of extract source items coupled to a start plate from a list of `SourceItemNames` string annotations to a single comma-separated list string in a `SourceItemNamesListString` text annotation. The reason for the change was that there is no guarantee that a retrieved list of annotation values will have the same order of items, as when the list was stored in the database, and a retained order is important in this case. See ticket:759 for more information. Follow this procedure: == 1. Changing start plate storage of source item names from a list of `SourceItemNames` annotations to a `SourceItemNamesListString` annotation. === a. Update to MeLuDI 1.2.1 === Among other things, this will add the `SourceItemNamesListString` text annotation for bioplates. === b. Copy existing `SourceItemNames` annotations for each start plate to a comma-separated list string `SourceItemNamesListString` annotation === i. Select BASE menu option `Biomaterial LIMS -> Bioplates` to display a list of bioplates. Find all start plates (items with bioplate type "`DNA Reaction plate`" and name equal to "`LP`" + a 5-figure number, that may include leading zeroes). ii. Select each start plate item in BASE, select tab "`Annotations`", and in table "`Primary annotations`", check option "`All annotations`". iii. For annotation `SourceItemNames`, copy the list of comma-separated string values before the colon (the colon should not be included) to the clipboard. iv. For annotation `SourceItemNamesListString`, click the "`Edit`" icon at the right end of the value field, to open an edit dialog window. In the edit dialog, paste the copied comma-separated list string to the value field. Remove leading and trailing white space (white space between the comma-separated values is OK). If needed, change the order of the source item names to the desired order. Click the "`Save`" button in the edit dialog, to save the new value and close the dialog window. The values of annotations `SourceItemNames` and `SourceItemNamesListString` should now look the same, although the first is a list of several string values, while the other is a single string with comma-separated values. The apparent similarity is a result of the way values are displayed in this table view, and if in doubt, open the edit dialog for an annotation to check the details.
