Transform a DMR with the Nifti Converter

It might happen that a DMR has an incorrect orientation. We can set the right orientation with the use of the Nifti-Converter. The procedure is as follows:

1 Load a DMR and start Plugins > Nifti Converter

2 select Global options: transformation

3 set the transformation matrix

4 set “apply to DMR”

5 click “Start Processing”

We will now go through each step. Open a DMR and start the Nifti Converter.

Set Global Options

In this tab, choose "Perform transformation function"
