Not enough memory. Please load a smaller dataset or use larger heap size.

今天在win7下裝weka發現運行不了，後來下載了jdk 1.6 64bit之後，正常安裝了 weka 3.7 現在正常運行，但是載入基因表達數據集後運行filter跳出錯誤警告如下：

 

Error Message

Not enough memory. Please load a smaller dataset or use larger heap size.

原因：

This error message appears when a user attempts to load or process a dataset that WEKA can not handle with the used heap size.

解決方案：

The Java heap size can be specified with the -Xmx option.

Let the classpath that contains a JAR file (weka.jar) be:

C:/Matlab/weka-3-5-7/

E.g., to use 256MB as heap size, the command line looks like this:

C:/Matlab/weka-3-5-7>java -Xmx256m -jar weka.jar
