http://imagej.nih.gov/ij/macros/RegressionTests.txtFor some reason I do not seem to be able to find the "RegressionTest.js" file
which is called in the 2nd line. Where can I download that from?
If I remove that line, sometimes the macro aborts with the embryos image under
java 1.6.0, claiming that there should be a stack to process (there is one
called embryos-1.jpg) the error is "Convert Stack to Images requires a stack".
Could this be a race condition?
Anyway, the first run of the macro before that error, which shows the progress
bar and stops for some secs shows "filter tester successful"
Java 1.6.0_35: -> 37 sec then if it does not abort, total: 47 sec to the end.
openkdk 1.7 : -> 508 sec total 522 to the end,
Java 1.8.0_51: -> 703 sec, total: 714 sec to the end.
15 times slower??
I am running linux 64bit in a very fast machine (the Ultilities>Benchmark Test
runs in 0.25 sec for any of the Java versions above, so I am puzzled by the
results above. I wonder what other users get.
Cheers
Gabriel
