The idea is to provide a "Channel concatenation" button in the default Analysis panel > Channel Functions.
After clicking this button, a dialog box should open, where the various Channels of different Channel Groups can be selected for the concatenation process. In the same dialog box, some options for the channel concatenation could be selected as well.
In this moment, some example scripts can be found in the discussion board for the concatenation of N Channels in M Groups. However, these scripts are quite cumbersome, not easy to customize, and providing too many optional features that are aiming to address shortcomings in the time or data channels to be concatenated.
It is a good practice, however, to correct first the issues in your Time and Data channels that prevent them of being concatenated properly.
The channel concatenation function would be a very useful feature, especially for engineers working with big datasets, that are increasingly recorded in contemporary data acquisition.
Typical examples of big datasets are vehicle CAN network data, recorded over an extended period of time (weeks, months).
Usually, these data are divided into multiple data files, which then need to be concatenated afterwards in order to cover a selected recording period, prior to further analysis of the data.
Dear wimdr, thanks for describing your usecase in your last abstract. We think we had solved this with DIAdem 2015 in the NAVIGATOR panel: You could append existing data in the data portal directly from files, if they have a similar structure. Please use the 'Open' dialog or the context menu. We think this is a better workflow than first load the data side-by-side into the data portal and then move it into existing channels. Please see the DIAdem-Help => Append data for conditions and rules to use this new DIAdem feature.
