Error in iSAX example?

[Hollis Wright]

Hello; I’m trying to use the iSAX example given (the TIE16 valve
example) and I seem to be running into an error. Specifically, the
code fails with the following error:

Exception in thread "main" java.lang.NoSuchMethodError:
weka.core.Instances.size()I at
edu.hawaii.jmotif.logic.sax.SAXFactory.instances2Discords(SAXFactory.java:
349) at
iSaxOutlierDetector.ISaxOutlierDetector.main(ISaxOutlierDetector.java:
22)

I have tried both weka 3.4 and 3.6 in the classpath and have the same
error. Any assistance would be appreciated.

Hi Hollis:

I'm sorry that code doesn't work. 

In short, there are ongoing API changes in WEKA - they have dropped support for this data format and picked it back again in 3.7.x. Ive just tested on 3-7-3 (old development version) and code works fine.

If you wonder why I am using this format - I've tried to collaborate with WEKA guys, and the format after all seems to be cool.

I don't know your level of proficiency in coding Java, but if you are limited to weka 3.4 or 3.6 - this issue is easy to get over, I will be glad to help.

Hi, Pavel; I'm actually pretty familiar with Java/Weka, as i used them heavily in my dissertation. Is it possible to get a source distribution of JMotif? I haven't used google code previously, so all I saw was the jar files. Thanks...

Sure, you just need to click on source tab (here): http://code.google.com/p/jmotif/source/checkout to browse and see changes. 

The links to checkout code on the page.

If you use Linux you type this:

svn checkout http://jmotif.googlecode.com/svn/trunk/ jmotif-read-only

If Windows you use TortoiseSVN or your IDE: Eclipse, NetBeans etc.

If you think the code can be improved - let me know - I'll give you a write access to repo.

Ok, great; I mostly just want to change this issue if it turns out to be an API change in Weka causing it. From the error it almost literally looks like a typo in the code. I'll check it out tomorrow and see what I see.
