+ <h3>Correcting the collation</h3>
+ 
+ <p>Occasionally, the collation as uploaded will contain errors, or need for some other reason to be modified. Within the relationship mapper, you can detach a sequence of readings and re-attach it elsewhere as a form of manual collation.</p>
+ 
+ <p>To detach one or more readings, drag with the mouse to select an area of the graph that includes all the affected readings. A dialog will pop up to ask which witnesses should be detached from the collation at that point. To attach a reading elsewhere, select it and drag it to the corresponding reading elsewhere in the graph, just as though you were making a relationship. There should be an option to specify that the readings are identical; select it.</p>
+ 
+ <p>At the moment, editing the graph in this manner can quickly lead to a rather untidy and confusing-looking graph. If at any point it becomes too difficult to follow, please re-load the relationship mapper.</p>
