how to use the ParticleAnalyzer class

Aryeh Weiss
Until now, I ave been using the ParticleAnalyer by running it from the
IJ.run method, and I want to start using it through its API.

I am embarrassed to say that I cannot figure out how to set it up - in
particular the options and measurements parameters. I looked for either
Java or Python examples, which I thought I saw in the past, and I cannot
find them.

Can someone who knows how to do this send to me some code snippets in
which options and measurements are set and then the PA is run?

I d not know why i am having so much trouble with this, but I cannot
seem to get my head around how to use the parameters in ij.measure, 
what goes into options and what goes into measurements in a constructor like

|ParticleAnalyzer
<https://imagej.nih.gov/ij/developer/api/ij/plugin/filter/ParticleAnalyzer.html#ParticleAnalyzer-int-int-ij.measure.ResultsTable-double-double->(int options,
int measurements, ResultsTable
<https://imagej.nih.gov/ij/developer/api/ij/measure/ResultsTable.html> rt,
double minSize, double maxSize)|

|Thanks in advance|

Hi Aryeh,

here is a basic JavaScript example for the ParticleAnalyzer:

rt = new ResultsTable();
imp = IJ.getImage();
pa = new ParticleAnalyzer(
   /*options=*/ 0,
   /*measurements=*/ Measurements.AREA+Measurements.MEAN,
   rt,
   /*minSize=*/ 0.0,
   /*maxSize=*/ 1.0e6,
   /*minCirc=*/ 0.0,
   /*maxCirc=*/ 1.0);
pa.analyze(imp);
rt.show("myResults");

For the measurement options, see

https://github.com/imagej/imagej1/blob/master/ij/measure/Measurements.java

Re: how to use the ParticleAnalyzer class

Aryeh Weiss
Thank you to Michael Schmid and Jerome Mutterer for your  quick
responses that solved my problem and greatly enlightened me. Michael's
response was sent to the list, and I also include below  Jerome's
response that provides a link to a number of examples on how to use the
ParticleAnalyzer class.

Best regards
