Hello,  
I am trying to merge files with vector data and with scalar data (defined on the same mesh), and then use Warp by Vector (to see each point displaced according to the vector data and colored according to scalar data). However, I can’t see them merged. Could someone please give an example of pipeline in GUI or Python file that perform this steps? Thank you!

The **Append Attributes** filter could be used.  
To do so, select the two loaded files in the **Pipeline Browser** and apply the **Append Attributes** filter.

What do you mean by select? They are both loaded; I applied both of them. However, when I use Append Attributes, it uses only one of them. What should I do? Thank you!

Select both while holding the `ctrl` key and clicking them. Then apply the filter as suggested above.
