---------------------+---------------------------------<br>
 Reporter:  sbl      |      Owner:  grass-dev@…<br>
     Type:  defect   |     Status:  new<br>
 Priority:  normal   |  Milestone:  7.8.1<br>
Component:  Imagery  |    Version:  git-releasebranch78<br>
 Keywords:  <a href="http://i.vi" rel="noreferrer" target="_blank">i.vi</a>     |        CPU:  All<br>
 Platform:  All      |<br>
---------------------+---------------------------------<br>
 <a href="http://i.vi" rel="noreferrer" target="_blank">i.vi</a> requires a red band in any case, even if e.g. NDWI does not need one.<br>
 So, in order to make the module run, a map has to be given also for the<br>
 red band. That seems like unexpected behavior to me.<br>
 Maybe better to leave all input bands optional and add a check for the<br>
 requested VI if required bands are provided...<br>
