ChnTMinTMaxCalc not always working

[Sarm]

Can anyone tell me why the ChnTMinTMaxCalc command does not work on the attached dataset "Data".  It does work for the attached dataset "Data2".  I can not determine that there is any difference between these datasets yet one is fine, the other will not output results from ChnTMinTMaxCalc.  Attached is a script to demonstrate that no results come from ChnTMinTMaxCalc for dataset "Data".  DIAdem 10.0.0f2541 TDM

Hi Sam,

the reason for your problem is the DAT header file. The stored values for min/max of the channels are not exact. There are some minor differences. If DIAdem loads the data it uses the stored min/max values if they are available. The easiest way to solve this problem is to recalculate the min/max values. You can use the command

Call CHNCHARACTERALL()

Despite we are using a tolerance to find the min/max values these differences are to high, but after the execution of this command  the ChnTMinTMaxCalc calculation is working fine.

Super, it works fine with the ChnCharacterAll command.  Thanks for the help.
