[kepler-dev] the ability to pause/adjust/restart a workflow

I don't know Edward if they decided it would be easier to write their own
workflow environment.  You could be right.  We didn't have a very long

I did encourage the gentleman to post to kepler-dev and talk about what he
needs and what his concerns were etc.

In trying to remember more of the conversations, he mentioned one of his
students had assessed Kepler about 4 weeks ago and it just didn't have what
they needed -- then I asked what did they need and he mentioned what I first
posted.  I got the impression he meant being able to actually explore and
look at data along the way, and maybe actually change or alter the course of
the workflow some based on that assessment -- but that is me guessing.

I don't think it was a matter of simply pausing and restarting, but being
able to assess things, adjust things, then restart from that point without
writing a new workflow or starting over etc.

Ptolemy II models can be paused, adjusted, and restarted...

There is a pause button right on the toolbar...

Let me guess: the person you talked to decided it would be
easier to create their own workflow environment rather than
add the functionality they need to Kepler, right?  I get that
a lot... Such people are not to be taken seriously...

someone from University of Zurich came up to me after my presentation and
specifically mentioned Kepler and was quite aware of it.  This was good.
However, the drawback was that they had decided against using it for their
needs because it lacks the specific ability to pause/adjust/restart a
workflow and they said this was critical to their work.  They are
computational chemists.

scientists as a result of some of my reviews and feedback from our
scientists at workshops.  And I believe Deana had identified that too before
I arrived on the project and maybe some of the rest of you too.  But I just
wanted to raise this issue again for future consideration.
