Hi Michael,
 
Thanks. Yes, I found that no maxima in the image was the problem.
Somehow the index in "if/else"and "for" seem not to work properly in the batch mode. In non batch mode, ImageJ choose the right ROI and do this operation properly. But in batch mode, it choose wrong one and create an empty image, so no maxima in that case.
Still I could not find the exact bug point....

Hi Sanghyun,

hmm, I can't reproduce your problem; this macro runs correctly with  
my version of ImageJ (1.45q6):

setBatchMode(true);
run("Blobs (25K)");
setThreshold(126, 255);
run ("Invert");
run("Find Maxima...", "noise=0 output=List exclude");
   a=getResult("X", 0);
   b=getResult("Y", 0);
print("nResults="+nResults()+" a,b="+a+","+b);

It won't work, however, if your image has no maxima.  getResult("X",  
0) will result in an error if there is no line 0 in the Results table  
because the table is empty.
