 Digitization
 ============
 
-Digitized figures from papers in the literature will be used to validate the ion channel models of ChannelWorm.
+Digitized figures from papers in the literature will be used to validate and refine the ion channel models of ChannelWorm.
 
 For example, a study which conducts [patch clamp recordings](https://en.wikipedia.org/wiki/Patch_clamp) will produce data that describe electrical properties of ion channels.
 This data is valuable to anyone modeling these ion channels; we can use actual ion channel data to guide our efforts toward biological realism, and incorporate it in [confirming that we are modeling what we are intending to](validation/).

 ## So why digitization?
 
 In a published paper, data is included in an expressive form, such as a visual plot, rather than as raw numerical data. This is not to say that we cannot *extract* the information and make use of it, however.
