Can DIAdem calculate dummy cumulative variance (DCV)?

I have several data channels that I would like to use to calculate the DCV.  The DCV is calculated after you have minimized the cumulative variance for each channel used in the calculation.  This is done by measuring the variance between 2 channels and then shifting one channel in time and re-calculating the variance until you have shift the second curve to a time point where the cumulative variance between the 2 channels is minimized.  This process is repeated with each new channel until all channels are aligned and the the DCV is calculated by measuring the mean of the channels and the std. dev.

 

Has anyone ever done this in DIAdem?  Is it possible.  It is a fairly common practice in dummy development.

 

Thanks

Hi Dan,

 

I have not see dummy cumulative variance calculated in DIAdem before, but let me do some more research to see if I can find anything. I'll get back to you.

Hello Don,

 

Unfortunately we have not heard about a DCV calculation.  With more information (especially algorithms and test data), we could look into this further.

HI Otmar,

 

How should I go about providing the algorithm and or test data?

 

Thanks,

Don,

 

If this would fit into an email attachment, please send it directly to me at my NI email address.Our email address format is FirstName.LastName@ni.com (no middle initials).

 

I can also provide an FTP server if the files are to big for email attachments.
