I am using ArcGIS Desktop and I have a 6-band raster.

How do I output a single-band raster whose values are the band number (1,2,3,4,5 or 6) of which band in the original raster contain the maximum (or minimum) value?

Accounting for ties would be a bonus.

Convert to grid format and use http://desktop.arcgis.com/en/arcmap/10.3/tools/spatial-analyst-toolbox/highest-position.htm on a list of resulting raster.
