47		-== How the Pipeline works ==
48		-
49	49	The design of the pipeline aims at interfacing a variety of general and specific analysis and processing steps in a flexible modular manner. Hence, it enables the pipeline to adapt to diverse types of data (e.g., electrical ECoG, or optical Calcium Imaging recordings) and to different analysis questions. This makes the analyses a) more reproducible and b) comparable amongst each other since they rely on the same stack of algorithms and any differences in the analysis are fully transparent.
50	50	The individual processing and analysis steps (**blocks**//, //see// //the arrow-connected elements below) are organized in sequential **stages**// (//see the columns below//). //Following along the stages, the analysis becomes more specific but also allows to branch off at after any stage, as each stage yields useful intermediate results and is autonomous so that it can be reused and recombined. Within each stage, there is a collection of blocks from which the user can select and arrange the analysis via a config file. Thus, the pipeline can be thought of as a curated database of methods on which an analysis can be constructed by drawing a path along the blocks and stages.

	114	+== Outlook ==
	115	+
	116	+* Using the **KnowledgeGraph API **to insert data directly from the Knowledge Graph into the pipeline and also register and store the corresponding results as Analysis Objects. Such Analysis Objects are to incorporate **Provenance Tracking, **using [[fairgraph>>https://github.com/HumanBrainProject/fairgraph]],** **to record the details of the processing and analysis steps.
	117	+* Adding support for the pipeline to make use of **HPC** resources when running on the collab.
	118	+* Further extending the available **methods** to address a wider variety of analysis objectives and support the processing of other datatypes. Additional documentation and guides should also make it easier for non-developers to contribute new method blocks.
	119	+* Extending the **application** of the pipeline to the analysis of other types of activity waves and oscillations.
	120	+* Integrating and co-developing new features of the underlying **software tools **[[Elephant>>https://elephant.readthedocs.io/en/latest/]], [[Neo>>https://neo.readthedocs.io/en/stable/]], [[Nix>>https://github.com/G-Node/nix]], [[Snakemake>>https://snakemake.readthedocs.io/en/stable/]].
