Created attachment 712 This includes [AllTypes.type], [tvm_filterFunctionals.node] and [LayerPipeline.pipe] Hi Robert, With regard to our discussion, here is the explanation of how to make files for the pipeline program that I wrote. There are three types of files, nodes, types and pipes. A node file (.node, just an xml file) that tells you what a node looks like. Every node contains a title, input and output. Of the latter, there can be any number, including zero. Every input/output has a class, i.e. data type. At the moment just one, in the future preferably more. The data type must be one of the supported data types [AllTypes.type]. Clearly, this list can be expanded. Rather than me writing down how this is implemented, just have a look at the example [tvm_filterFunctionals.node]. Tells you everything you need to know. So you need (a) type file(s) to make a node and node files to make a pipeline. Note that the pipeline doesn't know about the types. A pipeline save file [LayerPipeline.pipe] stores the type of nodes and their position in the GUI, its ports and links. Every port has an identifier and each link goes from identifier to identifier (which is just an int64 in hex). Every input port has an output port as well. The reason is that this makes it easier to pass on data that is unchanged but needs to be used in subsequent functions nonetheless (e.g. some reference volume). This is also the reason that the input and output ports are arranged in 'port pairs'. For an output argument, the left side of the pair is null. Bugzilla lets me upload only one file with this bug report, so I put all the text in one file, marked where each file begins. Let me know what you think of it! Best, Tim

I made a test script that should run stand-alone and using only data on disk (as discussed). Please see /home/common/matlab/fieldtrip/test/inspect_bug2892.m or https://code.google.com/p/fieldtrip/source/browse/trunk/test/inspect_bug2892.m?spec=svn10554&r=10554
