[kepler-users] newbie question

[Chad Berkley]

Hey Corinna,

Could you send me your workflow?  I can take a look and get back to you.

thanks,
chad

 Ok, here comes a real newbie question:
 
 I am trying to do something that looks like it should be really simple 
 and straight forward:
 
 open a database connection, run a query, disassemble the query and graph 
 a time series of numbers
 
 The database connection opens, and the query runs fine, but when I hook 
 it to the recordDisassembler it claims that the input type is not a 
 record but an array (I did set the output of the databaseQuery actor to 
 record).
 
 What am I doing wrong?
 
 thanks for your help
 Corinna

[kepler-users] Newbie question

Hi all,

I have a lot of different programs belonging to a software package.  
Developers want to use workflows to make
such programs work coordinately depending on user needs (so we only  
want to invoke command-line
applications. At the beginning all will be run on a desktop machine
so we don't need grids. We have been having a look at Kepler and  
Taverna. At this moment we think Kepler fits better
to our needs.

Based on that, the question is.. Do you know another software  
alternative which fits our needs?.

Thanks in advance,

Dear Jos?,

There are many other good workflow systems in existence, but I'd have
to agree with you that Kepler sounds like a good fit.  Taverna is a
good system, but is heavily centered on executing web services.  We've
done a lot of work in Kepler to create various versions of a command
line execution component that lets you launch a local shell command
and process its output effectively.  We've also created a number of
other script execution components, including components for executing
R scripts and Matlab scripts.  With these, you have access to the many
bridges that R and Matlab provide to other popular scientific software
packages that run on the local desktop.  Finally, there's the builtin
actors in Kepler like the Jython actor that lets you execute python
scripts -- I even think someone was working on a perl actor and asked
about it on the mailing list recently.

Pegasus is focused on executing grid jobs, taverna on web services.
Kepler can execute both of these as well, but also includes many
components focused on running on the local desktop.  Triana might fit
your needs, but I don't think they've done as much as we have in the
Kepler community on access to scientific scripting systems, but you
might want to check them out too.

Cheers,
Matt

Hi Guillaume,

One way to do this is by right-clicking on your actor and selecting  
Save In Library You will be prompted to give your actor a  
semantic annotation. After this your actor should display in the  
Component Tree.

Let me know if this doesn't work for you,
Derik

 Hello
 We have developped a GRIA actor for Kepler
 Currently, I am using Tools - Instantiate Component to add such a  
 component in my workflows.
 It would be easier for us to have it in the Component Tree of the  
 user interface, how to achieve this ?

 Thanks and Best Regards

 Guillaume
