Script

[Brad_Turpin]

Hi say,

I get the same error you report when the ChanName string can not be found at least 2 times in the Data Portal.  Here's a version that checks for that and logs the issues in the log file (below the script in the SCRIPT editor).

dim ChanList, ChanNames, ChanName, ResultGroup, ResultChannel
ChanNames = Array("force", "force_xyz", "Energy")
set ResultGroup = Data.Root.ChannelGroups.Add("Results")
Call ResultGroup.Activate()
FOR Each ChanName In ChanNames
  set ChanList = Data.GetChannels(ChanName)
  IF ChanList.Count > 1 THEN
    set ResultChannel = ResultGroup.Channels.Add("Mean_" & ChanName, DataTypeChnFloat64)
    call ChnAverage(ChanList, ResultChannel)
  ELSE
    LogFileWrite "Couldn't find enough channels of type: " & ChanName
  END IF
NEXT ' ChnName

Hello Brad,

Thank you for your answer , the script is now running , but i think that it doesn't calculate the mean, i only have one case named "result : as you can see in the figure attached : 'result')

However, i tried another script ( attached in the other figure named : another script') provided by Dia 791, what do you think about it? i think that it works

Hi say,

Your original request was for "the mean of three test[s]".  I understood you to want to calculate the mean of N channels that all shared the same channel name but were stored in N different groups.  That's what the script I sent you does-- you get one result channel for each original channel name.

If this is not what you're after, please try again to explain what you want.
