Batch automating sequences of images.

You can find the modified code here:

The support script is here, as well as in JJMack's previously linked .zip archive:

I added two extra blocks of code to JJMack's original script:

The original script was not processing in alphabetical order, it was mixing up the image sets, so I added a forced sort:

//////////////////////////////////////////////////////////////

             // Enforce Alpha-numeric Sort - ADDED BY STEPHEN A. MARSH 2019
             fileList.sort();
             
////////////////////////////////////////////////////////////// 

And here is the "major" addition, you will need to uncomment/remove the // double forward slashes from the line

//app.doAction("MyAction", "MyActionSet.atn");

Then replace the MyAction and MyActionSet.atn with your specific action.

                           var doc = app.activeDocument;
                           doc.activeLayer = doc.layers[doc.layers.length = 0]; // Select the top layer
                           var layerName = doc.activeLayer.name.replace(/[a-z]+$/ig, ''); // Regex to remove single or multiple consecutive case insensitive alphabetical characters from the end of the layer name when used in the filename
                           // doc.activeDocument.backgroundLayer.remove(); // Remove the Background layer
                           doc.activeLayer = doc.layers[doc.layers.length-1]; // Select the back layer
                           doc.activeLayer.remove(); // Remove the active layer
                           doc.channels.removeAll(); // delete alphas  
                           
////////////////////////////////////////////////////////////// 

                           // Play Action - ADDED BY STEPHEN A. MARSH 2019
                           //app.doAction("MyAction", "MyActionSet.atn"); // Change the action and action set as required
                           
                           // Or add additional code to do something else to the layered sequence stack before saving...
                           
//////////////////////////////////////////////////////////////  

                           //Save output file - MODIFIED BY STEPHEN A. MARSH 2019
						outputFile = outputFolder + "/" + layerName + " Final";
                        
//////////////////////////////////////////////////////////////  

OK, I’ll presume the following then:

* Single source folder

* Alphabetical sort

* No specific layer order if combined into a single-layered image

However, you also mentioned changing the file-name:

So, does the layered file need the suffix alphabetical character/letter removed so that the filename only consists of digits/numbers? Are there variations on file name patterns or is the naming consistent?
