Re: [chemclipse-dev] Help with Exception
When open a ChromatogramMSD file which contain only one scan, exception occured. 
(The .ocb file was attached.)

Caused by: java.lang.IllegalArgumentException: Given range is invalid
at org.swtchart.internal.axis.Axis.setRange(Axis.java:190)
at org.swtchart.internal.axis.Axis.setRange(Axis.java:156)

Another exception in making a test ChromatogramMSD. It seem these data model were tied with eclipse platform.

Hi Alex,

that's from the peak model.

The peak intensity model stores relative values. A peak consists of the peak intensity values and a peak maximum (e.g. a mass spectrum). The peak maximum has a total intensity, though each intensity along the retention time scale of the peak can be calculated by using the total intensity of the peak maximum multiplied by the relative intensity value at the given retention time.

Normally, the MAX_INTENSITY is 100.0f, see:
org.eclipse.chemclipse.model.core.IPeakIntensityValues

To calculate percentage values, the max values needs to be known. If other max values than 100.0f are used, you can run the normalize() method after putting your values to the model.

void normalize();


Best,
Philip

Hi all,

Anyone can help me out with this one?

Exception in thread "pool-1-thread-3" org.eclipse.chemclipse.model.exceptions.PeakException: There must be at least one intensity value stored with a relative intensity of IPeakIntensityValues.MAX_INTENSITY.
    at org.eclipse.chemclipse.model.core.AbstractPeakModel.checkModelConditions(AbstractPeakModel.java:403)

Im tying to build a dummy peak for JUnit and feeding the model like this:

PeakIntensityValues result = new PeakIntensityValues();
    for (int i = 1; i < 10; i++) {
        result.addIntensityValue(i, i);
    }
    return result;

Best,

Alex
