+Since version 1.4.0, RNA dots can be assigned to a nuclei and not onyl to a cell: if there is no cell/junction staining to determine the cell limits but only nuclear staining, it can be used as the reference instead.

 Assigning RNAs corresponds to attributing to each dot the same label as the cell we consider that it belongs to. Several methods can be used for an automatic selection, and manual assignment or correction can also be done.
 
+Since version 1.4.0, if there is no cellular staining but only nuclear staining, RNAs can be associated to their most likely nucleus in that case.
+
 ## Assignment methods:
 
 * `Projection`: assign each RNA to a cell by projection in Z. Thus, the assignment depends only on the X,Y position of the dot and on the junction segmentation. 
+This option is only proposed if there is a cellular staining.
 
 *  `ClosestNucleus`: assign each RNA to the cell of which the nucleus is the closest to the dot in 3D. The distance is calculated from the closest point of each nuclei to the RNA spot. 
+This option is only proposed if there is a nuclear staining.
 
 * `MixProjClosest`: assign each RNA either to the closest nuclei if the RNA spot is deep in z (closer to the nuclei) or by projecting it to the apical cells if the spot is close to the surface. 
+This option is only proposed if there is a cellular and nuclear staining.
 
 * `Hull`: to update
