Are you getting any java heap size error? (example: "Could not reserve enough space for object heap")

java -version will give you the verbose version information, which should indicate whether your installed JVM is a 32 or 64-bit build.

A 64-bit JVM should have no problem with the higher memory limits.

Also try updating to TASSEL 5.2.6 (the latest version)

I increased the heap size even though the data is not getting transformed.

Download 64x of the Java. Here is the link: http://javadl.sun.com/webapps/download/AutoDL?BundleId=87443

Before starting jvm just check how much RAM is available and then set memory accordingly.
