New channel type "calculation channel" in Data Portal

Status: Completed Submitted by Member on 06-08-2011 09:54 PM 17 Comment

Rather than a channel that has a "fixed" value (numeric or string), this new "calculation channel" type would be a function of other channels.  Currently, if Channel3 = Channel1 + Channel2, and then I change the values for either Channel1 or Channel2, I have to re-execute the calculation

 

ChnCalculate("Ch(""Channel3"") = Ch(""Channel1"") + Ch(""Channel2"")")

 

Now, if there was a "calculation channel" where I could define Channel 3 as "Channel1 + Channel2", I wouldn't need to perform this re-execution! 

 

Another way to explain is to have a channel that works like Excel calculation cells.  The cell calculation stays the same, and when the input cells change, the result cell is automatically updated. 

 

I'm not sure if I explained this well, please ask for clarification if necessary.

Diadem should use the tdms-format as default for saving

Save Data compressed (i.e. MDF4.1 compressed) to reduce disk space

Status: Completed Submitted by Member on 08-01-2017 08:31 AM 3 Comment

Preparatory having compressed TDM(s), the ready defined MDF4.1 could be used to save disk space.

DataFinder calculates channel characteristic values during index

Status: Completed Submitted by Member on 10-22-2012 07:12 AM 4 Comment

It might require too much computation time but I was wondering if the DataFinder could calculate and store such characteristic values as channel min/max during it's index. I would find this really helpful.

If it is not practical to do on the fly, how about an extra option on the context menu in Navigator - in addition to 'Re-Index File' etc there would be 'Calculate Characteristic Values' which would then calculate and save the valeus back to the files for the file/folder/drive selected.

Having Network Directories in DataFinder That Don't Hang When Network is Disconnected

Status: Completed Submitted by on 01-30-2012 11:39 AM 2 Comment

Having network directories available in the DataFinder is a great tool. However, if a network directory is added as a default search locations AND the network cable is unplugged, DIAdem will hang for a very long period of time. Windows commands are used to query for network locations. If not connected to the network, the timeout for these commands is quite large. 

 

While this is technically expected behavior, it is not ideal software functionality to hang if a network cable is unplugged.

Save Data optimized in Navigator

Status: Completed Submitted by Member on 12-19-2016 02:46 AM 1 Comment

In DIAdem 2015 a function to optimize the DataType was included to Analysis (ChnOptimizeDataType).

I think it would be very helpfull, to have this as a option while saving data.

The needed Discspace of optimized Data is just a fraction compared to storing in Float64.
