Hello Thomas,
yes there is a way to do that, but it requires to set a variable with a short VBS.
If a channel is loaded or created implicitely and expanded aftrewards DIAnem still remembers that the channel is implicite and tries to save it in that way.
To remind the type of channel, DIAdem uses the variable ChnDataType().
Use chndatatype(1) = "Explicite" to set the first channel to explicite (you will have to expand the channel first)
If you save the data afterwards, channel 1 will not be converted to implicite again.
Hope this answers qour question
regards
