strange behaviour of the results table

[Karel Jansseune-2]

Dear,

I run a macro that makes calculation in the results table inorder to
combine ROI's.
(A long story short:
calculations are made to create coordinates for the ROI's,and ROI's with
similar coordinates are than combined)
so far, the macro runs fine, but each time at startup, I get an error
saying that the results table is empty.
The second time the macro is run, everything works as it should.

I have already included a step to show the resultstable and to update it,
but this error persists.

Am I missing some setting here? Or could it be a mistake in my code?

Kind regards,

Karel

Yes, you must be missing something, but without seeing the code is nearly
impossible to say what it is.

This is the code that I use to set the coordinates.

The 2 first functions add an extra column to the result table, the third function combines all the ROI's that have the same coordiantes.
I included an image of the plants that we are analysing.




function addXcoordinates (binsX){

        minX = getResult('X',1);
        maxX = getResult('X',1);
        for(i=0;i<nResults;i++){
                if (getResult('X',i)<minX){
                        minX = getResult('X',i);
                        }
                if (getResult('X',i)>maxX){
                        maxX= getResult('X',i);
                        }
        }

        Xcoord = "Numeric X coordinate";
        setResult(Xcoord,0,NaN);
        binSizeX = (maxX - minX) / (binsX-1);
       
        for(i=0;i<nResults;i++){
                for (j = 0;j<binsX;j++){
                                Xval = getResult('X',i);
                                if ((minX + (j-0.5) * binSizeX <= Xval ) && (Xval <= minX + (j + 0.5) * binSizeX)){
                                        XCoordinate = j+1;
                                        }
                                //if (Xval == maxX){
                                        //XCoordinate = binsX;
                                        //}
                }
                setResult(Xcoord,i,XCoordinate);
        }
        updateResults;
}

function addYcoordinates (binsY){

        minY = getResult('Y',1);
        maxY = getResult('Y',1);
        for(i=0;i<nResults;i++){
                if (getResult('Y',i)<minY){
                        minY = getResult('Y',i);
                        }
                if (getResult('Y',i)>maxY){
                        maxY= getResult('Y',i);
                        }
        }

        Ycoord = "Numeric Y coordinate";
        setResult(Ycoord,0,NaN);
        binSizeY = (maxY - minY) / (binsY-1);

        for(i=0;i<nResults;i++){
                for (j = 0;j<binsY;j++){
                                Yval = getResult('Y',i);
                                if ((minY + (j-0.5)  * binSizeY <= Yval ) && (Yval <= minY + (j + 0.5) * binSizeY)){
                                        YCoordinate = j+1;
                                        }
                                //if (Yval == maxY){
                                        //YCoordinate = binsY;
                                        //}
                }
                setResult(Ycoord,i,YCoordinate);

Well, your results table is empy. Unless you fill it with some data, there is
no "X" that you can get (1st line).
You need to run the Analyze>Analyze Particle... command before running your
macro.

G.

[Karel Jansseune-2]

The macro I posted is part of a bigger macro, which includes a "Analyse
particles" step

It turns out now, that the macro moves to fast, so the resultstable wasn't
filled when the combineROI started,
I added an "wait(200)" step and I didn't got the problem anymore.

thank you anyhow for the help
