| NoRMFsupplied | error |
| | The input units for ranges have been set to keV but a redistribution matrix hasn't been supplied. |
| MoreThanOneStatMethod | error |
| | Only one statistical method, e.g. minimum counts, minimum S/N or ratio above background, can be specified |
| InvalidRangeString | error |
| | The ranges must be entered as '1-10' or '1:10' if specified in channels or as '2.0:4.53' or '2.0-4.53' if specified in keV. |
| EnergyOutOfRange | error |
| | The specified energy range is outside the range of energies contained in the spectrum |
| RegBinRange | error |
| | The start bin for regular binning must be >= 0 |
.
| IncompatibleTemplate | error |
| | The template spectrum has a different number of channels from spectrum to be grouped. |
| AmbiguousGrouping | error |
| | There has been a clash between the ranges and regular binning requested. |
| AlreadyGrouped | warning |
| | A bin which has been requested to be set bad by the setbad option has already been grouped and so will stay as a good channel.
corrective action: leave channel as good |
| NoMergeGroup | warning |
| | After grouping has completed and ungrouped channels are treated according to the lastbin parameter selection. Sometimes it is impossible to find a contiguous group to add a given channel to. Contiguous channels which fall in this category are used to form a new group.
corrective action: create a new group |
