Displaying only populated table data

[techerdone]

Hi,

I have a waveform that I want to designate with the chemical's name for that specific time. I have done this on the graph by creating a channel of strings and inputting the corresponding chemical name at the correct time and then using the "from channel" feature for the labels.

Now, what I want to do is display a table of the chemical names and their corresponding peak values at that time from the waveform. I can't figure out how to only display rows of data that are populated with a chemical name (a string).Let me know if I need to clarify this for further help. Thanks

Hi techerdone,

If I get you right, you are looking for something like a filter for the content of a channel. DIAdem doesn't have such a function as ready to use. You need to isolate this in separate channels.

Copy the channels you need to a new channel group. Analyze the text channel and set the value of it to "NoValue" if it is not a certain text. Then use the "Process NoValues" function ("Channel functions" in ANALYSIS) to eliminate all values you don't need (this includes all channels you would like to display). I hoe this can help.

Greetings
