 ====== Script ======
-THIS position should be used for a brief introduction (max 2 sentences!) of the logic, stating WHAT and WHY it is doing something.
+The Script uses [[https://www.lua.org/manual/5.1/index.html#index|Lua 5.1]] in order to read or modify header values of images. CCC values of a stack of images can be read by the Script and used as weighting factors in a different logic.
 ===== Usage =====
-Here, a general/generic description of HOW the logic is USED should be given. Try to be as general as possible, but also mention prerequisites, restrictions, advantages, requirements which are specific of this logic. Basically everything the user needs to know to successfully use this logic.
+The Script needs to be combined with the element [[eyes:logics:variable|]].
+At first a Variable is set up with the certain data type. In order to access a single image in a cow workflow the script needs to call the cow.io[#number of the image in the IO]. Then to read a header value of that image the script needs to be expanded by the name of the header in quotation marks ["image header values name"].
+**cow.VariableName = cow.io[#number of the image in the IO]["image header values name"]**
