The idea sounds really cool. I am hoping this can be achieved in next beta
release. As said, this is particularlly useful when user-defined processors
(i.e., I built a set of web services wrapping the AFNI tools for
Neuroinformatics) are heavily used in an experiment. For each AFNI service,
one typically needs to specify more than 5 input parameters, most of which are
not passed in from their preccedors.
Thanks.
