Erwin and Christopher,
CC'ed ice-dev for completeness.
I started putting together a plugin for ICE that
will run Triquetrum workflows. It was easiest to
do this with a fork of the main ICE repo so that
I can give Erwin commit privileges to push his
changes back.
The way that I am doing this for now is to create
an ICE plugin using our project generator. This
will be sufficient to demonstrate for the talk
that ICE and Triquetrum can talk to each other.
However, it is not the way that I want to do it
long term. The really sustainable way to do this
will leverage some upcoming workflow engine
updates that we are working on which will make it
possible to create compositions of whole workflow
engines.
Here are the instructions to get the fork and run
ICE from it:
1.) Create an empty workspace
3.) Switch to the next branch and import all projects
4.) Go to org.eclipse.ice.target.mars and set
mars.target as your target (unless you are doing this
with ICE, which already has all of the required bundles
set).
5.) Go to the org.eclipse.ice.repository project and
right-click and run the launch configuration product.* for
your OS. If you are using Windows or Mac, you will need to
add org.eclipse.ice.triquetrum to that configuration.
6.) Go to the ICE perspective and in the ItemViewer at
the left create the Triquetrum Item by clicking on the
green plus button. The Triquetrum Item is currently at the
bottom of the list that appears with an ugly name at the
moment. (See attached picture.)
You can edit the code for Triquetrum by modifying the
contents of the org.eclipse.ice.triquetrum bundle. I
suggest that we do everything in the Model Item for the
moment and don't mess with the launcher (no need really).
I think the way that this should work is that someone
creates a workflow in Triquetrum with the graphical tools.
Then, they open this Triquetrum model in ICE and they have
a list of Triquetrum workflows from which they can choose.
Once they pick one, the can choose something like "Launch
Triquetrum Workflow" from the process bar at the top, hit
Go! and the process() operation executes the workflow.
I have attached a data file that contains reflectivity data.
The x axis is the angle Q and the y axis is the specular
reflectivity. I don't know the units off-hand.
This is all I have time to do with this today and probably
until Friday, but I should still be able to answer questions.
If you can get ICE calling Triquetrum from
TriquetrumWorkflowItemModel.setupForm(), then the rest should
be very easy.
