Hi Ayla,

thank you for your reply and help, I read this links at scirun web yet. We need detailed description, how the interface scirun-matlab really works. How to transfer values in variables between matlab- scirun, how matlab works with the ports etc.

Here is a short description:
SCIRun exports its data types to Matlab by converting the datastructure of the dataflow objects into a matlab readable structure. Hence a SCIRun matrix becomes a 2D matlab matrix, a field becomes a structured matlab matrix in which each field encodes certain properties of the dataflow object.

The interface works by taking the input objects, (nrrds, fields, matrices, and bundles) converting them to matlab files, then matlab reads them in and code is executed and then the matlab variables are written out and then converted back into SCIRun objects.

For example - each component measures time, how long works. Is it possible to transfer this value from scirun to matlab please?

No we do not have support for that.

Could you send me some *srn file, which one includes interface matlab - scirun please?

Look into the example nets:

in the source distribution:


in the binary distribution:

example_nets/MatlabInterface (OSX)
C:\Program Files\SCIRun 4.x\src\Packages\MatlabInterface\nets (Windows)



Best regards!

Hi Martin,

Can you describe the problem you're having in more detail? Also, wehave some documentation for the ExportFieldsToMatlab module on our

) and the documentation for ImportFieldsFromMatlab describes which
SCIRun Field types are compatible with which Matlab matrix types
