[ome-users] More matlab questions

[Brian Ruttenberg]

I'm currently trying to integrate some matlab execution modules into our 
OME database, and I'm running into some trouble.  Hopefully someone out 
there can lend some insight...

I have a matlab function that outputs pixels and a string tag.  In our 
database, we have a semantic type called a PixelSet, which is just a 
label of the different operations that we have performed on a set of 
pixels.  So ideally, I would like this matlab analysis module to output 
directly into that semantic type with the pixel reference and the string 
tag of the operation performed.    However, I can't seem to get the two 
outputs go to the same database entry. 

For example, in my analysis module I have:

       .....
          <Declaration>
            <FormalInput Name="Pixels" SemanticTypeName="Pixels" Count="!"/>
            <FormalOutput Name="BinaryPixels" 
SemanticTypeName="PixelSet" Count="!"/>
             <FormalOutput Name="BinaryTag" SemanticTypeName="PixelSet" 
Count="!"/>
          </Declaration>
       
                  <ExecutionInstructions ExecutionGranularity="I" 
xmlns="http://www.openmicroscopy.org/XMLschemas/MLI/IR2/MLI.xsd" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
            <FunctionInputs>
                           <Input><PixelsArray 
FormalInput="Pixels"/></Input>
            </FunctionInputs>
            <FunctionOutputs>
                           <Output><PixelsArray 
FormalOutput="BinaryPixels" ConvertToDatatype="uint16"/></Output>
                           <Output><Scalar 
OutputLocation="BinaryTag.Tag"/></Output>
            </FunctionOutputs>
          </ExecutionInstructions>
     ....


Where PixelSet contains a pixel reference and a string tag.  But int the 
database, it is stored as:

ome=# select * from pixelset;
 attribute_id | image_id | module_execution_id |    tag    | pixels
--------------+----------+---------------------+-----------+--------
        .....
          222 |       17 |                  83 | default     |    220
          232 |       18 |                  84 | default     |    230
          725 |        1 |                 105 |                  |    722
          726 |        1 |                 105 | Binarized |
          730 |        2 |                 107 |                  |    727
          731 |        2 |                 107 | Binarized |
          735 |        3 |                 109 |                  |    732
          736 |        3 |                 109 | Binarized |
          740 |        4 |                 111 |                  |    737
          741 |        4 |                 111 | Binarized |
          745 |        5 |                 113 |                  |    742
          746 |        5 |                 113 | Binarized |

As you can see, the two outputs each have their own attribute ID's, but 
I would like to combine them so the Tags and the Pixels match up in the 
database. 

Hopefully I'm not way off on this, but any help would be greatly 
appreciated.  Thanks!
