Hi Herbie,
Thanks for that it's good to know you can use a string that contains the kernel. Presumably altering this slightly as below to add in a string from an array wouldn't work.
Kernel = newArray ("kernel1", "kernel2");
run( "Convolve...", "text1=["+kernel[0]+"] normalize stack" )
I'll play around with it tomorrow. I could always do it slightly less elegantly with a for loop and a series of if and else if statements to switch the kernel to Convolve with.
run( "Convolve...", "text1=["+kernel[0]+"] normalize stack" )
Thanks,
Matt

Good day Matt,
not sure whether it helps in your case, but I use to store the kernels
as a string in a file and then use:
kernel = File.openAsString( path2kernel );
run( "Convolve...", "text1=["+kernel+"] normalize stack" )
This should also work without storing the kernels in a file.
