What's up Utkarsh?
So I was able to write that plugin and convert my image to the
vtkImageData. However, I am having trouble visualizing the image.
However,
when I write out the output from my reader, the image gets written
correctly... Here are some pictures to show the differences. (All the
information for the images is exactly the same) Do you have an idea of
how I
can try to fix it? Thanks.

Re: [Paraview] File in pipeline browser has changed; best way to reload
Hi Alex, I'm using a little python macro to refresh the fileNames Property of all readers in the Pipeline. It is located here: https://github.com/richti83/ParaView_Reader_for_LIGGGHTS/blob/master/python_macros/update.py Feel free to use this as a starting point. Best, Christian.

Re: [Paraview] File in pipeline browser has changed; best way to reload
Hi Alex, there is a thread from around 2 years ago that proposed a couple of solutions. Especially if you are using a custom reader plugin this provides for a clean and user-friendly approach: http://public.kitware.com/pipermail/paraview/2013-June/028588.html http://public.kitware.com/pipermail/paraview/2013-June/028596.html (this is the solution we use) Regards, Michael On 05 May 2015, at 09:12 , Christian Richter christian.rich...@ovgu.demailto:christian.rich...@ovgu.de wrote: Hi Alex, I'm using a little python macro to refresh the fileNames Property of all readers in the Pipeline.
