Hello Thomas,

>is there a simple way to calculate the execution time of a macro ?

Try putting

start = getTime();

at the beginning of the macro code you wish to time and then

print((getTime()-start)/1000);  

at the end of the code.  Time is returned in milliseconds, this divides by 1000 to give runtime in seconds.

I will add this caveat from the description of getTime on the ImageJ homepage: "The granularity of the time varies considerably from one platform to the next. On Windows NT, 2K, XP it is about 10ms. On other Windows versions it can be as poor as 50ms. On many Unix platforms, including Mac OS X, it actually is 1ms. "

Hope this helps,
Christine
