Hi,

What is the best method to delete a channel from a structure from within sigTOOL? Can this be done interactively?

Thanks!

Mario.

The channels are stored in a cell array. You can not presently delete a channel from within the GUI. You can though draw selected channels using the Channel Manager

To "delete" a channel, from the GUI choose File->Export->To MATLAB. A variable, "channels" appears in the base workspace. Choose the channels you want e.g.
>>channels=channels{1,2,5:10,99};

then
>>plot(channels{:})
to set up a new view. You can then use File->Save As to create a new file.

Thanks Malcolm,

I got through the first bit, but it didn't occur to me to use the overloaded plot method. In my case it is useful because the data in some of the channels was unusable, while still very large.

A propos, I am amazed at how well SigTOOL works, considering it's matlab ;]

Mario.
