Data array path error

[Abhishek Telang]

Hello all,

I am getting the following error code while trying to use the find GBCD filter.

"DataContainerArray::getPrereqArrayFromPath Error at line 384. The DataArrayPath object was not valid meaning one of the strings in the object is empty. The path is ImageDataContainer||"

I converted the .ang 2D EBSD data file from hex grid to square grid and also created the Dream3D data file.

The read dream.3D file filter can read the data as seen in error code picture but I cannot select the correct data arrays from the drop down menu.

I am running Dream 3D 6.0 on Mac

How can I solve this problem?

Thanks,

Abhishek

Hi Abhishek,

According to the documentation, this filter needs both the image representation of the data and a surface representation of the data; this is why you cannot select anything for the face data, since you only have image data currently.  "Face" data here refers to data that lives on 2D polygons such as triangles.  You will need to create a surface mesh for you structure to be able to run any of the GBCD filters.  The filter that creates a surface mesh is called "Quick Surface Mesh".  You will probably also want to smooth the resulting mesh using the "Laplacian Smoothing" filter.  For more information on surface meshing, check out the "Surface Meshing" tutorial in the DREAM.3D help manual (the manual can be accessed by going to the Help > DREAM3D Help menu).  

hope that helps,
