Shifting or rotating a raster file, how?

GRASS GRASS user

Hi there,
  
  After patching two raster files, an uncontinuous edge arises on the
new patched layer. I guess one of them need to be shifted or even rotated so
they'll match each other. Is there any way I could have this done in GRASS?

Thanks in advance !

Use i.rectify or i.rectify2. There's an mage processing tutorial
somewhere on the moon to teach you how to do this.
