You'll have to edit the source code a little. Specifically the src/edu/lehigh/swat/bench/uba/Generator.java
Line 647 of Generator.java
contains the part System.getProperty("user.dir") + "\\" +
. Change it so that it looks as follows:
private void _generateDept(int univIndex, int index) {
String fileName = System.getProperty("user.dir") + "/" +
_getName(CS_C_UNIV, univIndex) + INDEX_DELIMITER + index + _getFileSuffix();
writer_.startFile(fileName);
This holds for version UBA1.7 of the generator.
