I originally was given the files in tif format which I can convert to tiff which I can select under Save Data. When I save as vtk, do I just changed the file name to have .vtk? I don’t see an option to “save as” or “convert to” so I just deleted tiff and replaced it with vtk. Should this be done for every file or for s\_C002T…tiff \> s\_C002T…vtk? Thank you

Did you select files from the _save data dialog_? The selection in _save data dialog_ does nothing indeed. Simply load the data to be converted and save as the type you want with a proper name.
Here is my _Files of type_ list when saving data:
You can see that there’re **.vtk .vti** etc, just choose the type you want and name it. I use windows10 OS.

Yes.

Thank you so much, I am now able to animate my data as a Slice. However, I was told that this should be 4D data, when I load the vtk folder and select volume I can see nothing, no matter which color map I use or how I edit the color map. When saving the data I selected “Write timestep as file series”, I thought this was correct but maybe it is not.

Since you were only given .tiff slices which are generally 3D data(2D+time), then you have to figure out which slices consist of a volume to gain 4D data(i.e. how to organize the dataset).

This happens because the data does not suit a volume representation, which depends on dataset.

This option is to save each timestep of a temporal dataset as a new file series(otherwise only current timestep gets converted). To get 4D data, you need to gather all slices with same T to get a volume(via paraview or manually), then name every volume in proper order.
