Hi Herbie,

Thank you for your effert and time. Unfortunately my code is not working yet.

The textfile thresholds is made, however in de debug screen it is stored as follows: file ="~0~". So it won't recognizes where it is stored I think. This is also the reason I think that nothing gets printed in it. When running this part of the code no error is given.

file=File.open(Output+"Thresholds.txt")

print(file, "Minimum threshold: "+lower + "\n")

Do you maybe have an idea how to solve this?

Thanks a lot.

Iris

Iris,

this is part 2 of my answer.

Here is the macro code:

/////////////////////////////////
waitForUser("set the threshold and press OK, or cancel to exit macro");
getThreshold( lower, upper );
print("your thresholds are: " + lower + " to "+ upper );

txt_file = File.open( "Thresholds.txt" );
print( txt_file, "Minimum threshold: " + lower + "\n" );
print( txt_file, "Maximum threshold: " + upper );
/////////////////////////////////

getNumber( "Minimum", lower );

Does the latter help with your last question?

Best

Herbie
