DIAdem Idea Exchange

Post an idea

Currently you can only search for one channel at the same time with the advanced search as shown in the first graphic. if you select two channels at once, no search results will be found.

It would be very helpful if you could search for several channels with different characteristics at once.

for example, one could look for measurements that contain a first channel with a particular property and at the same time contain a second channel with a different property. It would also be helpful if the different properties of the search were linked by setting the brackets.

here's an example

such a function would greatly facilitate the evaluation of large data volumes.

When I am loading multiple same-named channels into the Data Portal from a DataFinder Search Results list (after 'searching for channels'), if I load these channels into the data portal, by default they all load into the 'default' group, and because they have the same name, they are re-named inside the Data Portal with suffix numbers.

I think it would be better to create a new group in the Data Portal with the name of the group the channels belong to in their respective files, or at least provide this option.

By default, the datafinder is launched when Windows starts. This can be easily removed by msconfig.

When we run DIAdem, the datafinder pops up in the task bar, which is totally normal as DIAdem uses it for a number of tasks. But when it comes to closing DIAdem, the DataFinder still lives in the task bar. When I look at how much RAM it takes, I'm pretty much surprised about the 30MB used.

What about an general option where we could choose to close the DataFinder when DIAdem exits ?

On a more global note, what about adding a "Close" method to the datafinder object (no it does not exist, contrary to Connect and Open...) ?

Regards 😉

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 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.

Not having the DataFinder index anything except NI's folders by default on install would be extremely convenient. Optionally, this could also be a setting chosen on install.

Each of our users who installs the application immediately has every MS Excel file from their 'My Documents' folder indexed, which wouldn't really hurt anything except that most of these MS Excel files aren't true 'data' files. In my experience, most Excel files rarely store anything as simple as what could be stored in text-tab delimited format, so aren't easily or usefully indexed, so seems to confuse the DataFinder as it is unable to close them automatically once opened.

The results is dozens to hundreds of Excel.exe processes running in the background, until the machine runs out of memory or files, so we have had to make a point to disable all datafinder indexing on each and every install. We've scripted this process into our standard configuration, but if the user doesn't contact us right away, they suffer greatly from performance issues and blame DIAdem (rightly so).

I suspect that anyone who wants to use the DataFinder would want to do some manual configuration to specific folders, dataplugins, times of day to index, etc. which would make requiring setup perfectly acceptable to users who want to use it (and not waste resources for those that don't).

When selecting a matrix structure set of channels for the z-matrix, DIAdem currently allows a user to select the first channel when the triplet channel radio button is chosen, and then locks that first entry as the first Z channel in the z-matrix. When the user wants to select the last channel in the z-matrix, they then have to click the "..." box to the right of the greyed out box that has the first Z channel in the z-matrix displayed. I was going to suggest that R&D work on the ability to chose channels that are not consecutively arranged within the data portal. I feel it would be more intuitive to hold down CTRL and select the Z channels that make up the z-matrix.

Cheers!
