I'm developing a software using BioJava. Now I need to create a SymbolList with a really long sequence, and I uses: ************** SymbolList sbl = new SimpleSymbolList(dnaToke, ls); ************** 'ls' is a string of 10000000(10 millions) symbols, then I got an 'OutOfMemory' exception. Is this a problem with BioJava? How can I get around with that? Any advice is greatly appreciated. Cheers Angie
