This is an attempt to implement the feat application from the fsl fMRI package www.fmrib.ox.ac.uk/fsl/fsl/whatsnew.html into a Scufl workflow. Details are still being polished but the general structure is here. The main problem that we have with such workflows concerns data provenance. Each of the services is typically iterated on hundreds of data sets and keeping track of the produced files is a pain.
