 Samples are grouped by shipping (see [Ship Samples](user-guide/ship-samples)) if there are shippings for the project, and by age. Shipped samples can be included in the list of all samples or only be shown as part of their shipping.

 ### Create a Sample
 
-To add a sample to LiST, you first have to select the project it is associated with. That choice is not final, samples can be transferred later if necessary.

-For each sample, a target instrument has to be selected. That instrument's ID will be used to generate a sample ID. Synthesis steps in other instruments can be added later. Another part of the sample ID is the growth date, by default, this field is initiated with the current date. Once a sample has been created, the sample ID can't be changed in LiST. Should you need to change the date and the sample ID, you have to contact the LiST data manager.

 Samples are submitted when they have been synthesized and all synthesis data is available in LiST. This happens automatically after 30 days, if the sample is valid, i.e., the following data are available:
 
 * At least one synthesis activity exists.

-* There is growth recipe available.

-It might also happen that a sample exists where the growth recipe is simply not available. In that case we still need the sample, and a synthesis activity should be added with an estimated growth time, and then be submitted manually.

 Once submitted, no further growth or post-processing activities can be added, and those activities can no longer be changed.\
 Characterization activities however can be added to LiST any time, as well as Split activities.
