Increase heap size in java for weka

Question

I\'m trying to increase the heap size in java for weka which keeps crashing. I used the suggested line:

> java -Xmx500m -classpath

but

Answer 1

If you run weka from the command line but not through java i.e. typing weka into the command line, instead of typing

weka

specify the memory flag

weka -m 1024m

This will specify 1024 megabytes.
